What is plastic injection mold?

Plastic injection molds are designed as hollow metal blocks with cavities used to shape molten plastic through the injection process. There are many holes inside the mold, and the temperature can be controlled by means of oil, water or heater.

Gates in the mold allow molten plastic to flow in, which then fills the cavity through runners and gates. After cooling, the mold is opened, and the ejector pin of the injection molding machine is pushed by the top plate to further eject the molded part.

  • Guide Pins– Installed to one half of the plastic injection mold and align the two halves by entering the holes in the other half. the most function is to locate the core and cavity insert in right position, avoid steps on parting line of molding parts or mismatch between two halves of molds.
  • Runner– Connect the sprue bush to molding cavities, it is a passageway of flow material, the section shape is usually round or trapezoid.
  • Gate–The narrowest position of the runner, where the flow material enters the molding cavity. There are many different types, some will be broken from molding part when ejecting out. such as submarine gate, tunnel gate. Some need to be cut after molding. like tab gate, side gate and so on.
  • Sprue (Bush) – Tapered hole in the center of the plastic injection mold into which the flow material travel from the nozzle of injection machine to runners
  • Locating Ring– Locating the plastic injection mold on the fixed platen of injection machines, so that the injection nozzle lines up with the sprue bush.
  • Mould Cavity(include cavity and core)– The space in the mold shaped to produce molding product.
  • The ejector (Pins)– Push the runner and molding parts out of the mold
  • The Shot– Total amount of material into cavities, include runner and molding parts
  • Ejector plate/Ejector backplate: Just for hold the ejectors in the right position
  • Clamping plate: Clamping the mold to the platen of injection machines


We provide a wide range of services to help clients with all of the front-end work that goes into a product before actual production begins. Some of those services include preliminary design, material selection, pricing, mold design, evaluation and procurement, CAD/CAM, surface modeling, and communication with the customer’s engineering department. For each part, we manufacture we will do the DFM study and mold flow analysis which will improve and support the mold structure design.We bring you a combination of the best resources available; high technology equipment, quality workmanship, and program management and product development techniques that are flexible enough to meet the needs of your special requirements that can assist the molder or worker and save time and cost

Mold Flow

Quality products and services at the lowest cost and in the quickest time. A universal standard that every company must follow to compete in today’s markets. Every molded plastics part must run smoothly through product design, tool building, tryouts, manufacturing, assembly, field applications, and over the life of products. Our expertise in CAE (computer-aided engineering) in conjunction with the experience of hundreds of molded products provides a valuable link to reach the goal of producing quality products at the lowest cost and in the shortest time. Our engineers will analyze for mold filling, cooling, and warp (deformation) … for every part with the tooling design as well as scientifically validating key steps to make your product a success – designed and built right the very first time. Our unmatched expert approach to every project provides the best value in the long term and will save you cost and time.

Project Management

Project management is the key to the success and quality of the products ,A Project Engineer who has rich knowledge in tooling and plastic injection molding is appointed for each project. All of them have a good command of English.
