Plastic Injection Molding Service

It is of utmost importance to select the right mould tool for your project. The plastic injection mold is the vital link in the chain that holds the whole process together. It is the key to ensuring all the components in production arrive at the end-stage accurately and of high quality.

According to the complexity of the product, the injection time, the difficulty of demolding, and the requirements for production capacity select the appropriate material for the mould, design the appropriate number of cavities, and select the appropriate machine for injection production.

There may also be multiple cores and cavities in one mould tool, so that many components may be made within a single cycle of injection moulding.

Once your mold has been carefully designed and manufactured, the molding process includes the following basic steps:

• Step 1: Prepare plastic raw materials and dry the materials.
• Step 2: The raw material particles can be mixed with the masterbatch to create the correct colour for the design.
• Step 3: Pour the dried pellets into the hopper of the molding machine. Preheat the pellets in the barrel until they are completely melted to form a liquid resin.
• Step 4: Fix the injection mold on the machine, and perform it opening and closing tests. The purpose is to test whether the mold is installed properly and whether it opens and closes smoothly.
• Step 5: Adjust the injection pressure and temperature. The plastic raw materials in the molten state are injected into the mould cavity through the gate under huge pressure.
• Step 6: The material completes the solidification process of the plastic part within the set dwell time and cooling time.
• Step 7: The machine automatically opens the mold and ejects or pushes out the parts.
• Step 8: Set the robot to automatically grab the parts and place them on the designated workbench. Then start a new cycle.

The process is carried out as shown above, and products can be continuously manufactured through repeated cycles.

• 1. Control of raw materials. Before putting into production, check the quality of raw materials to avoid pollution and impurities.
• 2. Effective management of moulds. In many cases, the waste of production comes from the damage of the mold. In the process of mould production and preservation, a comprehensive record of the manufacturing process, mold trial conditions, production conditions, and maintenance conditions are comprehensively recorded.
• 3. Correct operation and adjustment of the injection molding machine. Injection temperature and pressure, mold temperature, injection time, etc., directly affect the quality of injection molded products.

Plastic injection molding is the most suitable service for a single part or final product which needs to be produced in large quantities (thousands to millions of pieces).

Various industries and applications rely on the production of objects and components produced by injection molding.

The frequently used items include auto parts, medical equipment and instruments, household appliances, small kitchen appliances, daily consumer goods, telecommunications electronics, computers, LED light lens, toys and game products, Packaging, industrial products, etc.

• Repeatability – the same shape can be produced in the millions.
• Accuracy – The manufactured product or part is not only repeatable, but can always maintain consistent tolerances and appearance.
• Capacity to Custom Parts – Special materials and complex processes can be customized to reflect many characteristics of injection molded parts.
• Manufacturing Efficiency – In the era of Industry 4.0, the production process can be adapted to large batches and shorter operating cycles. The injection molding machine is equipped with robots to meet 7/24 services.
• Sustainable Cost-Effective Production – The use of recyclable materials in the injection molding process makes the manufacturing process sustainable. Due to recyclability and availability, the raw materials used for injection molding reduce production costs.
