Utilizes screw-type plunger to force molten plastic material into a mold cavity Produces a solid or open-ended shape (typically a cavity and core shape) that conforms to the contour of the injection molded part. Injection molds require the use of thermoplastic or thermoset materials A parting line, sprue, and gate marks are present Ejector pin marks are usually present on injection molds 
Plastic injection molding is the preferred process for manufacturing plastic parts. Injection molds are used to create many things such as electronic housings, containers, bottle caps, automotive interiors, pocket combs, and most other plastic products available today. Plastic injection molds are ideal for producing high volumes of plastic parts, due to the ability to make multi-cavity injection molded parts, where multiple parts are made with one cycle. Some advantages of injection molding are high tolerances, repeatability, a wide range of material selection, low labor cost, minimal scrap losses, and little need to finish parts after molding. Some disadvantages of this process include an expensive tooling investment and the need to prototype, as some custom complex parts may encounter problems during the injection molding process such as warp or surface defects. Therefore, injection molded parts must be designed with careful molding consideration. All in all, as a professional plastic design, prototype manufacturing, molding, system assembly service contract manufacturing company. We are actually an extension of the customer product development team. We can provide seamless transition throughout the new product introduction cycle and provide full ownership of the product from design to build. We operate 7 injection molding equipment and related secondary operations in Shanghai, China. Integrated system manufacturing units can meet all product development needs, from prototype to full production. One order, the assembly of a production site system has brought many benefits to the customer, and over the past 20 years has also invested a lot of money, including plastic and prototyping of concurrent engineering; improved mold / plastic design, interface, and bonding; Faster time to market; no inter-company marking; and lower shipping costs. Systems necessary to support such efforts, including supply management, test development, data tracking, inventory services, etc.
