• How to source a plastic injection molding company in China?

    Plastic injection molding is the process using polymers or plastic resins that when heated, melted and injected under high pressure into a custom injection mold, will produce plastic parts to be utilized in product manufacturing. The manufacturing process can be a complicated one and there are many factors such as industry needs, specifications, end-users time/budget constrains to consider when choosing a plastic injection molder in China that best suits your production requirements. Volume Specialization & Capacity: With more than10000 injection molders of different size all over China, selecting the best injection company for your project can be a chanllenging task. The best is to start with narrowing down your options according to your volume and size requirements. High volume molders specialize in project requiring over 500,000 parts and typically produce parts requiring small-sized molds and press under 350 Ton. Usually the injection machines are equipped with robot systems to increase efficiency while saving more pennies. Low to moderate volume molders…

  • Coolant Expansion Tank

    This is the bottom of Coolant Expansion Tank for a branded automotive company. The material is PP. The part features with two screws. We could use either automated unscrewing system or hand load inserts to release the screws. Since this part is supplied to the after sales 4s car companies, the quantity is not that big.  We use hand load inserts to save manufacturing cost for clients.  For the water tank, the key technology is the part must be flat without any deform and assembly holes must be aligned perfectly. If there is any warp, the two parts could not be vibrated-welding together and water leaks. In order to solve the issue, firstly we have to run mold flow to do a pre-warp analysis so that the warp degree could be calculated and gate position decided. Mold flow is only an assistant tool in theory. Sometimes, mold flow result differs…

  • Gate Design-HS Plastic Mold Shop

    What proper gate design is important? The gate serves as the entrance to the mould cavity and should be designed to permit the injection mold to fill easily. It is very important to follow below gate considerations while picking gate location at the early stage of plastic mould design. Gates should not be placed where part-bonding or impact will take place in use. The gate area will usually have higher residual stresses than the rest of the part due to the packing that takes place. Therefore, it will be weaker than the rest of the part. Position the gate to minimize trimming problems. Scissor-type gate cutters, kept sharp, will work smoothly and leave no “blemish” marks. If possible, gate into the thickest section to avoid incomplete fill or sink marks. This will also minimize flow marks and distortion associated with setting into a thick section from a thin one. Position the gate so that venting…

  • How can you make mold slide comes out of lifter?

    It is rare to see the structure of slide coming out of lifter in plastic injection molds. We are not experts, but we just design a typical mechanism that works quite well based on our experience.  Hope that it helps you. Mold Design Concept If we use common mold slide, the steel circled in red get stuck. And the undercut could not be released with this. How to design lifter head?   Green block is lifter with a prominent tail while the purple block is slide which is to release undercut and drive lifter to release undercut downwards. Further explanation on slide out of lifter in plastic injection mold Mold lifter needs a limit screw to limit the stroke of lifter travelling down while the spring is to prevent lifter from moving right with slide The science of structure of slide from lifter   Angel lifter drive slide to move right And…

  • Why we need Prototype?

    Prototyping is an important step in the process of New Product Development. Prototypes can be inexpensively prepared by CNC machining stock shapes, by thermo-forming them from sheet stock, or simple injection molding tools can be made from soft steel or aluminum. In addition to providing a three dimensional presentation of the design, a prototype allows: Subjecting the part to the chemical and mechanical environment it will endure in real life Accelerated testing for part life Checking compatibility with anticipated secondary assembly operations How to protoype? Prototype molds may be simple or complex, steel or aluminum. Injection molded prototypes from molds that have cooling channels can supply cycle time estimates and guidelines for commercial tooling. Determination of shrinkage factors, optimum gate sizes, vent locations and effect of mold temperature should also be established. Molded prototypes are preferred because flow orientation may influence performance. The latter is particularly important in glass-filled compositions.HS Mold excels in…
