Exploring new technologies in plastic injection molding will do wonders for your business. And for the production of your concept of a product. With these new techniques. The design and function of your plastic parts will be efficient.
If you would like to know the latest plastic injection molding technologies, then this article is for you!

Injection molding is a constantly evolving technology, with new innovations and applications emerging all the time. Here are some recent technology innovations and applications of injection molding:

Additive manufacturing:

Additive manufacturing, or 3D printing, is being used in conjunction with injection molding to create complex molds and parts. This technology allows for rapid prototyping and customization, as well as the creation of unique shapes and designs.

Micro-injection molding:

Micro-injection molding is a specialized form of injection molding that is used to produce very small parts with high precision. This technology is being used in the medical industry to create components for surgical instruments, as well as in the electronics industry to produce miniature connectors and sensors.

Multi-component molding:

Multi-component molding, also known as overmolding, is a process that allows for the creation of parts with multiple materials or colors. This technology is being used in the automotive industry to produce parts with soft-touch surfaces and in the consumer goods industry to create products with unique designs and textures.

Sustainable materials:

Injection molding is being used to produce parts and products using sustainable materials such as bioplastics and recycled plastics. This technology is helping to reduce the environmental impact of manufacturing and increase the use of renewable resources.

Overall, injection molding is a versatile technology that is being used in a wide range of industries and applications. Ongoing innovation and development are helping to improve the process, reduce costs, and increase efficiency.

Does all injection mold need a hot runner?

 Injection molding is a widely used manufacturing process in various industries. It involves injecting molten material into a mold cavity to create a desired shape. One of the key considerations in injection molding is whether or not to use a hot runner system.

A hot runner system is a set of heated components that deliver molten material to the mold cavity. It consists of a manifold, nozzles, and heaters that keep the material hot and flowing. The purpose of a hot runner system is to eliminate waste and improve efficiency. By keeping the material hot and in a constant flow, there is less material waste and shorter cycle times.

However, not all injection molds require a hot runner system. The decision to use a hot runner system depends on several factors, including the size and complexity of the part being molded, the material being used, and the production volume.

For small parts with simple designs, a hot runner system may not be necessary. Cold runner systems, which use unheated channels to deliver the material, may be sufficient. Cold runner systems are generally less expensive and easier to maintain than hot runner systems.

For larger parts with complex designs, a hot runner system may be necessary to ensure proper filling of the mold cavity. Hot runner systems can also help prevent defects such as warping, sink marks, and flow lines.

The material being used also plays a role in the decision to use a hot runner system. Certain materials, such as thermoset plastics, may require a hot runner system to prevent premature curing or solidification.

Finally, the production volume must be considered when deciding whether or not to use a hot runner system. Hot runner systems are generally more expensive to purchase and maintain than cold runner systems. If the production volume is low, it may not be cost-effective to use a hot runner system.

In conclusion, not all injection molds require a hot runner system. The decision to use a hot runner system depends on several factors including the size and complexity of the part being molded, the material being used, and the production volume. It is important to carefully consider these factors when deciding on the best injection molding process for your specific application.

Custom insert molding

 

Various insert molding part use in all industry

Insert Molding (or insert moulding) in China is similar to multi-shot molding in that it results in the combination of two or more resins into a single product. Each resin is molded separately in an individual mold. And is transferred either by a robot or manually to subsequent molding operations for the additional resins. Insert molding is better suited for lower volume applications than multi-shot molding due to lower capital investment requirements. Typical applications include ‘soft-touch’ materials molded onto an enclosure (drill housing or handle) or multiple colors/materials molded together for aesthetic or functional purposes. we have broad experience in the development and manufacture of overmold products.
insert molding in China is generally much more affordable than in the West (about 50% lower in China, 30% lower in Taiwan) But of course, the whole process has to be carefully monitored to avoid disappointments.

we will devise the appropriate insert mold/mould making strategy for you. We have different ways for a complex small product and a large insert moulding tool. If you need to have real insert molded parts in hand within 2 weeks. Our prototyping team services have very cost-competitive.For the local insert molding or Export

If your company wants lower tooling prices. But still needs the flexibility of insert molding at home we can ship you the moulds. Built according to the specifications of your injection machines. Overall costs (tooling, parts & shipping) are generally about 30% lower. When we do the insert molded parts outside as well.

Let us re-engineer your insert molding parts for lower tooling costs.
In our product design process, we use our principles allow us to make design decisions based on actual manufacturing methods and costs. Which of course leads to more realistic decisions and better cost optimization than applying them when the design is already frozen. Our engineers strictly supervise any redesign effort to make sure that the final part still meets Western aesthetic expectations.

Insert molding material 

Insert molding (or “insert moulding”) is just one of the specialized plastic injection service delivery methods that insert molding and OVERMOLDING are the same as traditional injection molding.
Insert molding is the process of forming or forming plastic parts around other nonplastic parts or inserts
Insert inserts are usually simple metal objects. Such as nuts or stamping parts, and some special items that can be inserted into the complex motor Similarly. Non-metallic materials can also be used to insert molded inserts.
