Six stages of injection mold process in China
injection mold process stages:
Clamping, glue, pressure maintaining and cooling, mould and products.
The above process, again and again, can batch periodically to produce products. Thermosetting plastic and rubber molding including the same process,
but a thermoplastic material barrel temperature is low, the injection pressure is higher, the mould is heated, finished material injection in the mold of the subject to curing or curing process, and then strike off the membrane.
The trend of the current processing technology is developing towards the direction of the high and new technology, these technologies include micro injection molding, high filling compound injection, water injection, mixed with a variety of special injection molding process, foam injection molding,
mold technology, simulation technology, etc.
The temperature control
Injection molding equipment and mold manufacturing in china
1．Nitrogen-treated barrel temperature, injection molding process, the need to control the temperature of the
cylinder temperature, nozzle temperature, and mould temperature, etc. The first two main influence plastic plasticizing temperature and flow,
and then the temperature are mainly influenced by plastic flow and cooling. Each kind of plastic flow with different temperature, the same kind of plastic,
due to different sources or brand, the flow temperature, and decomposition temperature is little different, this is due to the different average
molecular weight and molecular weight distribution, plastic in different type of injection machine of plasticizing process is also different, so choose the cylinder temperature is not
the same.
2. The nozzle temperature, nozzle temperature is usually slightly lower than expected tube maximum temperature, this is to prevent the molten
material in straight through the nozzle may be "salivate phenomenon". Nozzle temperature also cannot too low, otherwise, it will cause the early setting
of melting and the nozzle clogging, or due to early coagulation material into the cavity affect the performance of the products.
3．Pictures of injection molds temperature, mold temperature inner performance and apparent impact on the
quality of products. Mold temperature is determined by the size of the plastic, of crystalline products and structure, performance requirements,
and other process conditions (melt temperature, injection speed, and injection pressure, molding cycle, etc.).
Pressure control
In the process of injection molding pressure including plasticizing and injection pressure, and directly affects the quality of plasticizing and plastic products.
1．plasticizing pressure: (back pressure) adopts a screw injection machine, screw at the top of the molten material in the screw rotating backpressure is called the plasticizing, which is also called backpressure. The size of the
pressure can be found on the overflow valve to adjust the hydraulic system. In injection, the size of the plasticizing pressure is depending upon the
design of the screw, the product quality requirements, and the type of plastic and needs to change, if the situation and the screw rotation speed is
constant, increase plasticizing pressure will strengthen shearing action, which will raise the temperature of the melt, but will reduce the plasticizing efficiency, increase the current and leakage flow, increase the driving power.
In addition, increase plasticizing pressure often can make the melt temperature uniformity, color mixing and discharge gas in the melt. general Injection molding in the operation of the pressure curve, the plasticizing pressure shall be on the premise of guarantee the quality of the product is lower, the better,
the specific values vary with the varieties of the plastic, but usually rarely more than 20 kg/cm2.
2. Injection molding pressure: in the current production, almost all the injection pressure of the injection machine is in piston or screw at the top of the plastic on the pressure (by oil pressure conversion) shall prevail. Injection pressure in injection molding, the role of is, to overcome the flow resistance
of plastic flowing from the cylinder cavity, given the rate of molten material molding and compaction of molten material.

Why injection molds use hot runners?
Why injection molds use hot runners?
After years of development, injection molds
have become one of the preferred molds for manufacturing in all walks of life
around the world, especially in the developed countries of Europe and The United States, which have advanced in the industry. The most important thing to
mention is the use of hot runner technology in injection molds.
1, hot runner technology shortens the
injection molding cycle
Because there is no limitation of the cooling time of the main channel and the secondary flow channel, the injection
mold can be ejected in time after being solidified. Many thin-walled product
molding cycles produced with hot runner molds can be completed in less than 8
seconds.
2, eliminating subsequent processes is
conducive to production automation.
After the workpiece is formed by the hot
runner mold, it is the finished product, and there is no need to trim the gate
and recycle the cold glue lane. Conducive to production automation. Many
foreign manufacturers have combined hot runners with automation to
significantly increase production efficiency.
3, hot runner technology saves plastic raw
materials
In the traditional mold injection, the
nozzle material is produced. The high plastic product is not allowed to use the
water material (recycled secondary material). Because the reuse of the nozzle
material will degrade the structure and performance of the plastic part, the
reuse will affect the product quality. There is no cold runner in the hot
runner mold, so no nozzle material is produced (fees are required). This is
especially significant for applications where the price of plastics is
expensive. In fact, the major hot runner manufacturers in the world have
experienced rapid development in the world when oil and plastic raw materials
are expensive because hot runner technology is reducing materials and reducing
materials. Fees, an effective way to save costs.
Expand the application of injection molding
process
Many advanced plastic molding processes
have been developed based on hot runner technology. Such as PET preforming,
multi-color co-injection in the mold, a variety of materials co-injection
process
4, reduce the defective products of
injection molds and improves product quality
During the hot runner mold forming process,
the plastic melt temperature is accurately controlled in the runner system. The
plastic can flow into the cavities in a more uniform state, resulting in a
consistent quality plastic part. The hot runner molding plastic parts have good
quality, low residual stress after demolding, small deformation of plastic
parts, and greatly improved surface appearance of injection molded products.
Therefore, many high-quality products on the market are produced by hot runner molds.
Many familiar plastic parts, such as telephone casings, mobile phone cases,
printer cases, computers, and automobiles are produced using hot runner molds.

Design points for injection molding parts
Design points for injection molding parts
In the injection molding process, due to
the uneven cooling and uneven shrinkage of the plastic in the cavity and the
unreasonable structural design of the injection molded part, it is easy to
cause various defects of the product:
Shrinkage, weld marks, pores, deformation,
napping, top injury, flash.
In order to obtain high-quality injection
molding products, we must fully consider the structural processability when
designing the products. The following is a combination of the main structural
characteristics of the injection molding products to analyze the methods to
avoid injection defects. Design points for injection molding parts
1 mold opening direction and parting line
Each injection molding product must first
determine its mold opening direction and parting line at the beginning of the
design to ensure that the core pulling mechanism is minimized and the influence
of the parting line on the appearance is eliminated.
1.1 After the mold opening direction
is determined, the reinforcement ribs, snaps, protrusions, and other structures
of the product are designed to be consistent with the mold opening direction as
much as possible to avoid the core pulling to reduce the seam line and prolong
the life of the mold.
1.2, For example, the direction of the mold
opening of the bumper is generally the direction of the body coordinate,. If
the mold opening direction is designed to be inconsistent with the χ axis, the
angle must be indicated in the product drawing.
1.3 After the mold opening direction is
determined, the appropriate parting line can be selected to improve the
appearance and performance.
2 draft angle
2.1 Appropriate draft angle can avoid
product pulling. The smooth surface should have a draft angle greater than 0.5
degrees, a fine grain surface greater than 1 degree, and a rough grain surface
greater than 1.5 degrees.
2.2 Appropriate draft angle can avoid
product top injury.
2.3 Deep cavity structure product design
When the outer surface slope is required to be smaller than the inner surface
slope, to ensure that the mold core is not biased during injection, to obtain a
uniform product wall thickness, and to ensure the material density strength of
the product opening.
3 product wall thickness
3.1 All kinds of plastics have
a certain wall thickness range, generally 0.5 ~ 4mm, when the wall thickness
exceeds 4mm, it will cause the cooling time is too long, resulting in shrinkage
and other issues should consider changing the product structure.
3.2 Uneven wall thickness will cause
surface shrinkage.
3.3 Uneven wall thickness can cause pores
and weld lines.
4 stiffeners
4.1 Reasonable application of ribs can
increase product rigidity and reduce deformation.
4.2 The thickness of the ribs must
be less than 1/3 of the wall thickness of the product, otherwise the surface
will be reduced.

New purchasing strategies in the global economic slowdown
What will happen to the world economy in 2019? A large
number of uncertain factors have left the world economy in a fog, and overall,
anxiety and optimism coexist. Basically, the global economy will slow down in
2019. Since the beginning of 2018, emerging market economies have suffered from
capital outflows, weakening the economies of emerging countries, leading to
currency depreciation, rising inflation, and reduced household purchasing
power. In the second half of the year, some emerging markets broke out in a
currency crisis, geopolitical situations were once again tense, trade frictions
escalated, and the risk of a resurgence of the crisis was reshaping new growth
patterns through different forms.
In the global economic downturn in 2019, companies have
become increasingly difficult to survive. Especially for large and medium-sized
enterprises, faced with high labor costs, rental pressures, and rising raw
material prices. How to find the right supplier, reduce the procurement cost
and ensure the quality?
1, how to reduce procurement costs
Currently, companies are in a highly competitive and
rapidly changing environment, and competition has caused the industry's average
profit to fall. It is increasingly difficult for companies to establish or
maintain sustainable competitive advantage through sales and production; there
is still room for development in the procurement field that has been neglected
for many years.
Effectively reducing the overall cost of procurement and
integrating supplier capabilities through strategic procurement will become an
important source for leading companies to continuously reduce procurement costs
and enhance their competitive advantage. Therefore, the focus of procurement is
on how to choose suppliers, especially the supplier price comparison that pays
more attention to the transaction process. Through the competition of
suppliers, choose the lower price as the partner. Perhaps the blind pursuit of low
prices may lead to a decline in quality. If you cooperate with CN-MOULDING, you
don't have to worry about this problem. CN-MOULDING is a typical small and
medium-sized enterprise in China. The company is not too large. It is a real
manufacturing enterprise. CN-MOULDING can supply customers directly,
eliminating all the difference in the middle and reducing costs. The company coordinates Shanghai has geographical advantages, convenient import and export,
familiar with business operations, saving time and cost.
2, how to choose low-cost high-quality suppliers
Taking CN-MOULDING as an example, an injection mold
company was established in 1997 and has been a small and medium-sized private
enterprise for 20 years. Since its establishment, it has been focusing on mold
manufacturing and injection molding. Since 2001, it has been engaged in the foreign
trade business. It has a large customer base and recognition in Europe and
America. With its exquisite technology and rich experience, it has been
provided to customers in more than ten countries and regions. solution:
1. Help customers to properly adjust the wall thickness
of the product and find the best balance between product quality and production
cost.
2, predicting the appearance of weld defects, gas marks,
trapped gas, and other defects,
3, predict and control on the mold. Predict product
distortion,
4, Help customers to improve the product assembly
structure, the front design to avoid deformation.
5, rationally arrange the glue and cooling system to
achieve the best process and the most economical investment.
6, to provide optimized production process parameters to
help customers solve the problem of product injection production.
The following mold is produced by CN-MOULDING for
American customers. It is bulky, thin wall, complex in structure, high in
precision, and more difficult to de-mold the gas roof unit. At that time,
CN-MOULDING was not the first choice partner of customers, but more inclined to
have large companies on a large scale. In the eyes of customers, big companies
mean high quality, high standard, on-time delivery, after-sales service and so
on. But ignoring an important issue is the cost of procurement, the quality of
the mold is excellent, is the price equally satisfactory?
After the customer revealed that the original mold price
was 680,000 RMB, far exceeding their budget. Then the friends around me came to
Shanghai CN-MOULDING company to visit and inspect, and offered the quotation on
the spot, the total price was 476,000 RMB. They said that it is hard to
believe, after all, the price is only 70% of the previous company. It is also
doubtful that such a low price can really be achieved? Can you really guarantee
the quality of the mold? Is the after-sales service guaranteed? Wait for a series
of questions. CN-MOULDING has shown that the larger and more difficult mold
cases that have been done before have been shown to customers. Although
CN-MOULDING is a small and medium-sized enterprise, it has 20 years of
experience in mold manufacturing, and the cooperative companies have many
world-class companies. The business has also spread to more than ten countries
and regions. Numerous successful cooperation cases have enabled customers to
have confidence that CN-MOULDING is a professional, experienced and trustworthy
mold manufacturing company.
China's small businesses are fundamental to the vitality
of production
There are tens of thousands of small and medium-sized
enterprises in China. SMEs are the most dynamic and innovative enterprise
groups in China. At the same time, SMEs provide more than 50% of tax revenue,
create more than 60% of GDP, and complete more than 70% of invention patents,
providing 80%. More than % of urban jobs. SMEs have a pivotal position and have
unique advantages. With reasonable prices, rich experience and reliable quality,
they are gradually replacing the original large enterprises.
CN-MOULDING is a small and medium-sized enterprise in
China that is dynamic, innovative, and professional, and directly supplied to
foreign countries. In 2015, we obtained ISO9001:2000 quality certification!
With 20 years of integrity, 20 years of experience, and 20 years of quality
assurance and after-sales protection.

mold life what is factor affect
mold life what is factor affect
The first factor affecting the life of an injection mold is dissolution failure. The injection molding alloys commonly used in injection mold factories are zinc alloys, aluminum alloys, magnesium alloys, and copper alloys, as well as pure aluminum injection molding. Zn, Al, and Mg are more active metal elements, and they have a better affinity with mold materials, especially Al is easy to bite. When the hardness of the mold is high, the corrosion resistance is good, and if the molding surface has a soft point, the corrosion resistance is disadvantageous.
The second reason that affects the life of injection molds is thermal fatigue, which leads to failure of crack damage. During injection molding, the mold is repeatedly subjected to the action of stimulating heat, and the forming surface and its interior are deformed, causing repeated cyclic thermal stresses. The damage of the structure and the loss of toughness lead to the appearance of microcracks and continue to expand. Once the cracks are enlarged, the molten metal liquid is squeezed in, and the repeated mechanical stress causes the cracks to accelerate and expand. For this purpose, on the one hand, the mould must be sufficiently preheated at the beginning of the injection. In addition, the mold must be kept in a certain operating temperature range during the injection molding process to avoid early crack failure. At the same time, it is necessary to ensure that the internal factors before and during the production of the mold are not problematic. Due to actual production, most mold failures are a crack failure.
The third reason that affects the life of the injection mold is the failure of the fracture. Under the action of the injection force, the mold will crack at the weakest point, especially the trace marks or electro machining marks on the molding surface are not polished, or Fine cracks appear first at the clear corners of the molding. When there is a brittle phase or coarse grain in the grain boundary, it is easy to break. The crack propagates rapidly during brittle fracture, which is a dangerous factor for the failure of the mold. For this reason, on the one hand, scratches, electric machining marks, etc. on the mold surface must be polished, even if it is in the casting system, it must be polished. In addition, the mold material used is required to have high strength, good plasticity, impact toughness, and fracture toughness.
After understanding the three factors that affect the service life of injection molds, CNMOULDING injection mold factory can adjust these problems in the process of manufacturing, avoiding the influence of these factors in advance, and making better quality molds. It not only greatly improves the efficiency of production, but also saves the production cost of the enterprise.
There are also some reasons that affect the precision of the mold.
