Where does the excellent quality of plastic parts come from? From the screening of raw materials to the micrometer calibration of mold accuracy; From the repeated debugging of injection parameters to the rigorous testing of finished products. Being strict step by step is the key to not losing trust.

To be successful as a plastic mold factory, we must take three steps. The first step is to make a good mold, the second step is to control the quality of injection molding, and the third step is to improve efficiency while maintaining quality. Choosing us means choosing the peace of mind of "guaranteed quality and improved efficiency."

Although both sliders and lifters are used for mold core pulling, what are the differences in their usage scenarios?Encountering undercuts on the outside of plastic parts, especially those with deep undercuts and large areas? Sliders can help! Encountering undercuts on the inside, with small spaces and shallow undercuts? Lifters are better!

In the field of injection mold manufacturing, we ensure the precision of every cavity, stabilize every injection parameter, uphold excellent quality, and hope to gain market reputation and long-term cooperation with customers.We always adhere to the original aspiration of precision and efficiency, aiming to bring you the most satisfactory cooperation experience.

A qualified injection mold has hidden secrets in every link from production to delivery. Dimensional accuracy, surface quality, molding effect, service life, every detail is related to mold quality. If the acceptance is not done well, it will delay production and increase costs after delivery! Choose GV MOLD to help you accurately control the quality of each mold!

How to optimize the mold to reduce weld marks? Use multi-point gates to shorten the melt flow distance (gate reconstruction); use trapezoidal or circular cross-section runners to reduce flow resistance and heat loss (runner optimization); add exhaust inserts to deep cavity molds to avoid air entrapment at weld marks (exhaust design); set heating plates at places where weld marks are likely to appear to extend the melt time.

Some people think that the fewer times of mold trials, the better the mold quality? In fact, the real value of mold trials is to discover mold design defects and adjust injection molding parameters. Through mold trials, potential problems such as product shrinkage, flash, and dimensional deviation can be exposed to avoid losses during mass production. The key to mold trials is not "less trials" but "one trial solves one problem."（Fewer mold trials ≠better mold quality）

How to avoid shrinkage of injection molded products? Remember 3 core principles1. The pressure should be "hard": Sufficient pressure and time are the key to offset shrinkage.2. The wall thickness should be "even": Uniform wall thickness design reduces shrinkage differences from the source.3. Cooling should be "fast": Fast and uniform cooling can solidify the surface and limit internal shrinkage deformation.

In injection molding, the purpose of heating first and then cooling is to optimize material properties and molding quality through temperature control. If the heating is uneven, the material may degrade and turn yellow, affecting performance. If the cooling is insufficient, the product will deform later due to residual internal stress.

Why is high-precision equipment so important for high-precision mold manufacturing? High-precision equipment ensures the accuracy of mold dimensions and surface finish, which is crucial to mold performance and product quality. Stable equipment can ensure the consistency of mold parts in mass production and avoid assembly problems caused by individual differences.
