1. High-Strength Bonding: The plastic encapsulates the insert with high strength, ensuring superior pull-out force and torque resistance, thereby preventing any loosening or detachment.  

2. Cost Efficiency: By eliminating post-molding assembly processes, this method reduces labor costs and minimizes assembly errors, thus significantly enhancing production efficiency.  

3. High-Precision Molding: Precision-engineered molds guarantee accurate positioning of the insert and uniform encapsulation of the plastic, meeting stringent engineering requirements.  

4. Wide Insert Compatibility: This technology supports a variety of materials for inserts, including metals (such as copper, aluminum, and stainless steel) and non-metallic options, addressing diverse industry needs.  

5. Material Versatility: It is compatible with both thermoplastics (e.g., ABS, PC, PA, POM) and thermosetting plastics (e.g., phenolic resins), fulfilling various performance requirements across applications.  

CNMOULDING’s Core Competencies

1. Advanced Mold Design and Manufacturing  

CAD/CAM/CAE simulation is utilized to optimize the mold structure, ensuring stability and enhancing the accuracy of insert positioning.  

High-precision CNC machining, EDM (Electrical Discharge Machining), and mirror polishing are employed to guarantee mold durability and superior product surface quality.  

2. Mature Insert Molding Process  

Automated systems for insert placement improve production efficiency and maintain consistency in manufacturing processes.  

Rigorous process control over parameters such as temperature, pressure, and injection speed effectively prevents issues like insert misalignment and insufficient plastic filling.  

3. Rigorous Quality Inspection  

Advanced inspection methods, including 3D scanning, pull-out tests, torque tests, and others, ensure that the bonding strength of inserts complies with industry standards (ISO 9001, IATF 16949).  

4. Wide Industry Applications

General Rules:

These ratios are estimates only. The pricing can vary greatly with cavitation and the complexity of the parts and second operations. Second Operations can involve anything from cleaning parts, overmolding, painting, drilling holes, pad printing, screen printing, partial sub-assemblies, etc. Please mail or call us to get a specific quote on your part.

Freight – The larger the parts become, the more of a factor freight from China becomes. Therefore, if parts can not be “nested” well medium and larger parts become much more expensive in China.

Volume – In general, we can run any pieces per run per shipment. For less expensive parts, the volume requirement may be much higher.

Lead Time – Production lead-time is about 3-5 weeks for our production, but for freight, you must add on 4-6 weeks. Buying container loads will greatly reduce your freight costs.

The false Chinese injection mold companies on the Internet

 When you are trying to find a Chinese injection mold companies on the Internet, after you search for ” Injection mold China in GOOGLE”, “injection molding company China” and so on, Google gives you the result is ” some companies tell you he comes from the United States, then there are many associates and partners in China, some companies will tell you, I am a Chinese injection molding company, we can do everything that you want to, he can provide.

As a Chinese mold owner with a conscience. I can definitely tell you that you find only a trading company, a trader, or a Liberal profession. Never blame Google. Google only gives you information, but he doesn’t have the ability to tell you the truth. These false deals are to make a difference between you and the Chinese injection molding company. In order to maximize profits, they will desperately lower domestic production factory prices. They will find some China small mold factory, with simple equipment and rough processing mode to lower the price. The accuracy and quality of your products are not guaranteed, perhaps you will tell me I really visit the factory. It’s a big company, the equipment, and the staff is very good, I check the injection mold quality there by myself.

  

 

I have to tell you, how do you know the whole mold and injection molding processing is done in this factory? Do you believe you can get $10 for a $1 product?

 

The real mold manufacturing plant

 

As an export mold and injection molded parts with 20 years of history, the real mold manufacturing plant, I would like to share a little experience with you.

1.Don’t believe that a Chinese injection mold company will have representative offices abroad.

2.No Chinese company will have an Associates with a foreign company. It’s just another customer form.

3.Each company is specialized in some types of injection molds and plastic molding products. Which will be nothing, this is not professional.

4.These fake companies are Internet marketing experts. You can easily find them on the GOOGLE home page.

5.The cheapest is not necessarily the real producer. There are many small factories for 1-5 people in China. Their prices are so cheap that you can’t imagine them. Of course, their quality is also cheap to your imagination.

More tips to find a really china manufacturing company, you can read our article about “Buying-Mould-and-Plastic-Injection-Molding-Directly-from-China-Company“, it will give you helpful

Overmolding Insert molding in China

 

Plastic molding process:

The overmolding is one of China's plastic molding processing methods. With plastic material or parison as raw material. make its external force by heating and a method of the shape of the products needed.

Overmolding is the piece, pipe, plate, such as plastic material, heating in a kind of rubber state, deformation by an external force. And moulding for all kinds of simple shapes. Then through cooling stereotypes and products. Over-molding including the hollow blow molding. Thermoforming, stretching film-forming method. such as only applies to thermoplastic plastic molding. Chinese over-molding is in molding on the basis of a method.

Mainly includes the following several forming methods:

Thermoforming

Hot forming is a thermoplastic plastic sheet that is heated to softening, the gas pressure, liquid pressure. Or mechanical pressure, using the appropriate tooling. Or jig and make its products a molding method. The plastic thermoforming method is many, generally can be divided into:

Injection Molding using a single-mode (male die and female die) or to Die. Using plus mechanical pressure or weight, to make all kinds of products from the sheet forming method. It is different from processing molding. This method is suitable for all thermoplastics.

Differential pressure molding using single-mode (male Die and female Die) or to Die. Also don't have to Die. In the gas under the action of pressure difference. Make the heating to soft plastic sheets with mould surface. Cooling is made after forming methods of various kinds of products. It can be divided into vacuum forming and differential pressure molding.

Thermoforming is especially suitable for thin walls, the large surface area of the manufacturing of the product. The commonly used plastic varieties have various types of polystyrene, organic glass, PVC, ABS, polyethylene, polypropylene, polyamide, polycarbonate, polyethylene terephthalate, etc.

Thermoforming equipment including clamping system, heating system, vacuum. And compressed air system and forming mould, etc.

Biaxial tensile

To make molecular reorientation of thermoplastic film or plate, etc. Especially above the glass transition temperature of the bidirectional tensile process. Stretch orientation between the glass transition temperature and the melting point of the polymer. After directional tensile and rapid cooling to room temperature, the film or monofilament. The drawing direction has a lot to improve mechanical properties.

Suitable for directional stretching of the polymer is polyvinyl chloride (PVC), polyethylene terephthalate. Polyvinylidene chloride, poly (methyl methacrylate, polyethylene, polypropylene, polystyrene, and some of the styrene copolymer.

Overmolding Insert molding in China: Insert Molding

Insert Molding is a thermoplastic material or stock under pressure for products with mold the molding method. In the plastic molding process of molten (softening) under temperature (below the melting point at least 10-20 ℃). Solid-phase forming. Including plastic of non-crystalline class above the glass transition temperature. A melting point below the high elastic area processing is often called thermoforming. And below the glass transition temperature is called cold forming or room temperature molding processing. Also often called cold working methods or room temperature plasticity of plastic processing.

The method has the following advantages: a short production cycle. Improve the toughness and strength of products. Simple equipment can produce large and super large products. Cost reduction. The defect is: hard to produce complex shapes. The precision of products. It is difficult to control the production process. The products are easy to be out of shape, craze.

Solid-phase forming includes sheet roll, deep drawing or sheet stamping, hydraulic forming, extrusion, cold stamping, roll forming, etc.
