What are the precautions during mold trial? 1. Whether the mold opening and closing is smooth and whether the ejection is smooth. 2.pay attention to the position of the gate of the mold and the way of feeding glue, the...

The melt temperature can be measured at the nozzle or using the air jet method. The temperature setting of the injection cylinder depends on the melt temperature, screw speed, back pressure, injection volume and injection molding cycle. If you have...

1. Defects in the plastic injection mold design cause bubbles in the injection mold 2. The parting surface of the injection plastic mold lacks the necessary exhaust holes or the exhaust holes are insufficient, blocked, poorly positioned, and there are...

ABS is synthesized from three chemical monomers of acrylonitrile, butadiene and styrene. Each monomer has different characteristics: acrylonitrile has high strength, thermal stability and chemical stability; butadiene has toughness and impact resistance; styrene has easy processing, high finish and high...

1. Traditional mold making methods The traditional mold-making technology is mostly based on the sample mold (mother mold), using copy methods (such as casting, spraying, electroforming, composite material pouring, etc.) to manufacture the main working parts of the mold (convex,...

1. Two-dimensional drawings must meet the national standards for mechanical drawing Use PRO / E software to produce the two-dimensional map, and the file configuration content should be unified. Drawing line width, font size and line should be unified, thick...

We are often asked how we make injection molds, and more specifically, how we make injection molds. The cost and time required to produce traditional mass production injection molds is the result of the need to maximize productivity and minimize...

1. Design of mold release angle in mold processing The rubber parts must have a sufficient release angle to avoid top whiteness, top scratches and whitening. The release angle is related to the performance of the rubber compound and the...

Gate design in plastic mold processing The flow is the shortest flow from the middle of the gate to the various parts of the rubber parts. The choice of the position of the gate and the pouring form of the...

ABS resin refers to acrylonitrile-butadiene-styrene copolymer. ABS is an acronym for Acrylonitrile Butadiene Styrene. It is a thermoplastic polymer material with high strength, good toughness and easy processing. It is used to prepare various parts such as instruments, electrical appliances,...
