Plastic Injection Molding Service
The plastic injection molding is the most common method of part manufacturing. It’s a manufacturing process for producing parts from both thermoplastic and thermosetting plastic materials. Material is fed into a heated barrel, mixed, and forced into a mold cavity where it cools and hardens to the configuration of the cavity. After a product is designed, usually by an industrial designer or engineer, molds are made by a moldmaker from metal, usually either steel or aluminum, and precision-machined to form the features of the desired part. It is widely used for manufacturing a variety of parts. With over 10 years experience on injection molding products. Common materials used in injection molding are as PC, PS, PE, PVC, PE, PP, ABS, Rubber, Acetal. We have a mature process technique and a unique view point in manufacturing plastic mold. For any project, we will take full sprite to design and develop the products by our professional team, include material purchasing,sample trial round, process build up, package design, transportation arrange and the molding design. We have a professional mould-making factory. As we get the RFQ from customer, we will invite the engineer to review the product drawing to come out a reasonable solution in making the mould, so that to ensure the product quality and the lowest price to customer.



Our capabilities are wide ranging and we can produce precision micro sized plastic parts and large injection molded parts up to 30 kgs. The machining scale is from 50t to 1500t. even if the products are over our ability, we also can outsource to our partner for supporting.

Our products is involved in Automobile, Furniture, Cell Phone, Notebook & Computer, Lighting, Electrical Appliances, Packaging Equipment, Toys, Playground, Advertising, Stationery, Housings/Covers/Cases/Enclosures, Containers/Buckets/Bottles/Cans/Tanks, Pallets & Trays and more.

We can promise to our every customer, all items we produce is the best in quality and lowest in price. Our service attitude is customer is the first!

In order to adapt to customer’s requirement, we pass below certification: ISO9001, ISO14001, TS16949, ISO13485, etc.
For the lead time, The regular production lead time for plastic injection molded part is:
20 days to finish the mold, after the mold has been finished, it will be put into the injection molding equipment for testing. Normally there will be some slight adjustments, which will take around 1 week to 10 days.
After the mold testing result is good, then it will be used to produce some samples to clients to confirm the quality, this process will take 1 or 2 days.


We will deliver these physical samples to clients, so that they can see the products directly and feel the quality in hands. Sometimes clients also need to test the assembly with other components. Only after the approval of these samples, we will then move forward to the mass production stage, which quality will be the same with the approved samples. The mass production lead time will depend on the part size and order quantity. We will put an estimate production lead time information on our quotation sheets so the clients would have a general idea about the time schedule.



For injection molded parts, some aspects might influence the surface appearance, such like gating position, parting line location, ejector pins positions, this is why we will confirm all these positions with clients before the actual production.We can also make some surface treatments to the mold, such like polishing, mirror polishing, matt finish and adding textures, which will be confirmed with clients before production as well.

For some thicker areas of the products, there might be some shrinkage or flow marks after molding. Our design and engineering team will fully analyze the design in great details before production, if they foresee any shrinkage or flow mark problems, we will inform the clients and help the clients to update the design better to avoid such issues.
