  • Custom Plastic Injection Mold Gate Types
    Custom Plastic Injection Mold Gate Types

    PTMS as an professional plastic injection mold company in china, we have much experience in plastic injection mold making, always provide high quality custom plastic injection mold to the worldwide customers. The gate is very important for injection mould, we will share some data of injection mold gate types. The two main gate systems are manually trimmed gates and automatically trimmed gates. The following examples show where they are used: Sprue gate: Used for large components, the gate mark is visible in component and no runner is required. e.g.: bucket molding (backside cylindrical gate mark visible and can be felt). Edge gate: Most suitable for square, rectangular components Ring gate: Most suitable for cylindrical components to eliminate weld line defect Diaphragm gate: Most suitable for hollow, cylindrical components Tab gate: Most suitable for solid, thick components Submarine gate: Used when auto de-gating is required to reduce cycle time Reverse taper sprue gate (Pin gate): Generally used in three plate molds. If you need top quality plastic moulds, the plastic injection moulders should design perfect gate for the injection mould, for more details please visit our website ptms-mold.com, we will share more knowledge about injection mold.

  • Some Elements of Custom Plastic Injection Mold
    Some Elements of Custom Plastic Injection Mold

    As a china plastic injection mold company, PTMS have much experience in plastic injection mold making, so we can make high quality custom plastic injection mold as customers’ request, as a plastic injection moulders, we would like to share other elements of plastic injection mold for the worldwide people. The rest injection mold elements as below. Core back plate. It holds the core insert in place and acts as a "stiffener". It is usually made of mild steel. Guide pillar and guide bush. The guide pillar and guide bush align the fixed and moving halves of a mold in each cycle. The material cases are usually made of medium carbon steel and will have higher hardness. Ejector guide pillar and guide bush. These components ensure the alignment of the ejector assembly so that the ejector pins are not damaged. They are usually made of CHMCS. The guide pillar typically has higher hardness than the guide bush. Ejector plate. This holds the ejector pins and is usually made of mild steel. Ejector back plate. It prevents the ejector pins from disengaging; usually of mild steel material. Heel blocks. Provides a gap for the ejector assembly, so that the finished component ejects from the core. Usually made of mild steel. Bottom plate. Clamps the bottom half of the mold with the fixed half of the molding machine; usually made of mild steel. Centering bush. Provides alignment between the bottom plate and the core back plate; usually made of CHMCS. Rest button. Supports the ejection assembly and reduces the area of contact between the ejection assembly and the bottom plate. It is most helpful when cleaning the injection molding machine, which is essential to ensure an "unmarked" finished component. Small foreign particles sticking to the bottom plate may cause ejection pins to project out from the core and result in ejection pin marks on the component.

  • Plastic Injection Mold Elements
    Plastic Injection Mold Elements

    Plastic injection mold industry is very important for our life, but most people do not know the injection mold elements, so we will share some elements of plastic injection mold for the worldwide people.   The plastic injection mold is made of: Register ring: Aligns injection molding machine screws with the injection mold. Usually made of case-hardened, medium carbon steel material (CHMCS). Sprue bush: The bush has a taper hole of 3°to 5°and is usually made of CHMCS. The material enters the mold through the sprue bush. Top plate: It is used to clamp the top half of the mold to the moving half of the molding machine and is usually made of mild steel. Cavity plate: The plate used to create a cavity (via a gap) that will be filled with the plastic material and form the plastic component. Usually made of mild steel. Core plate: The core plate projects into the cavity place and creates hollow portions in the plastic component. This core plate is usually made of hardened hot die P20 steel without hardening after core machining. Sprue puller bush: The sprue puller bush is used to accommodate the sprue puller pin; usually made of CHMCS. Sprue puller pin: The sprue puller pin pulls the sprue from the sprue bush. It is usually made of CHMCS   Above is just some elements of injection mold, as a plastic injection mold company in china, PTMS would like to make high quality custom plastic injection mold to the customers, for more details please visit our website ptms-mold.com. 

  • Plastic Injection Mould Design Consideration
    Plastic Injection Mould Design Consideration

    Plastic parts is widely used in many industries, so plastic injection mold is very important for plastic parts production, how to design perfect injection mold? In the fact, there are many design considerations in injection mold designing, so we will share some details as below.   Draft: Required in both the core and cavity for easy ejection of the finished component Shrinkage allowance: Depends on shrinkage property of material core and cavity size Cooling circuit: In order to reduce the cycle time, water circulates through holes drilled in both the core and cavity plates. Ejection gap: The gap between the ejector plate face and core back plate face should hold dimension within the core. It must allow component to be fully removed from the mold. Air vents: Removes gases entrapped between core and cavity (usually less than 0.05 mm gap), because excessive gaps can result in flash defects. Mold polishing: The core, cavity, runner and sprue should have good surface finish and should be polished along material flow direction. Mold filling: The gate should be placed such that the component is filled from the thicker section to thinner section.   PTMS as one of china plastic injection moulders, we have much experience in custom plastic injection mold making and injection molding, also can design perfect injection mold for the customers, if you need high quality plastic moulds, please contact us, for more details visit our website ptms-mold.com, project RFQ to sales@ptms-mold.com. We will make better injection mold solution for you!
