China Home Appliance Plastic Injection Mould Toolmakers

China Injection Mould Toolmakers Company

Injection molding is a well-established manufacturing process. Many industries widely use it, including electronics, automotive, medical, and household products. This method offers high precision, efficiency, low cost, and design flexibility. As 3D printing technology keeps developing, the design and making of injection molds are also changing and improving.

Next, the injection molding machine pushes the melted plastic material from the injection barrel into the mold. The mold usually consists of an upper mold and a lower mold that form a closed injection cavity.

During the injection process, the plastic material enters the mold cavity. Machine applies a specific amount of pressure. This pressure helps fill the material tightly. It prevents voids and defects.

The main steps in the injection mold toolmakers' process include: charging and melting of the plastic raw material, filling of the mold, cooling and curing, and removing the finished product from the mold.

First, pre-prepared plastic granules are added to the hopper of the injection molding machine through a charging device. Then, the plastic raw material is heated and melted by means of a screw and heater to a molten state that is ready for injection.

During the cooling and curing stage, this machine will control the temperature of the mold through the cooling system to gradually cure the plastic material. The cooling time depends on the characteristics of the plastic material and the size of the product, usually longer for larger sizes. After the plastic is fully cured, the product is removed and subjected to the next step of processing and handling, such as removing residual edges, trimming edges, applying surface treatment, or assembly.

Injection Mould Toolmakers Processing Advantages and Features

1. High efficiency:

Injection mould processing cycle time is short, the injection mold machine can achieve rapid opening and closing and injection cycle, suitable for large-scale volume production, that in a short period of time can produce hundreds of high-quality products.

2. Versatility:

Plastic injection mold tooling processing can manufacture household products of various shapes and sizes to meet the needs of simple parts to complex geometries, and a wide range of products can be achieved through accurate injection mold design and mold machining.

3. High precision:

The injection molds made with CNC machine tools and hardened steel can ensure the high precision and quality of the products and meet the strict quality standards.

4. High degree of automation:

The injection molding machine equipment used in the injection molding process has a high degree of automation, which can realize automated production operations, reduce manual operation, can quickly change the mold, flexible to adapt to the production needs of custom molded plastic parts, and improve production efficiency.

5. Wide choice of materials:

Plastic processing can use a variety of plastic materials, such as PP, PC, ABS, etc., to meet the performance needs of different household products.

6. Cost Effectiveness:

Although the initial mold cost is high, once it is put into production, the cost per piece will decrease with the increase of production, especially suitable for mass production.

7. Save on subsequent processing:

Plastic injection mold tooling can be completed in the same process of product molding and most of the subsequent processing, such as inlay, threading, lettering, etc., reducing the secondary processing links.

8. Good quality consistency:

Due to the high degree of automation of injection molding processing, product quality is less affected by human factors, ensuring product consistency.

Injection molding is a well-established manufacturing process. Many industries widely use it, including electronics, automotive, medical, and household products. This method offers high precision, efficiency, low cost, and design flexibility. As 3D printing technology keeps developing, the design and making of injection molds are also changing and improving.

For example, multi-cavity mold design can further improve productivity and shorten cycle time. In the future, injection mould toolmakers will still be important. They will help improve production efficiency, lower costs, and enhance product quality.
