In injection mold manufacturing, which is the key to the early design? Or the later manufacturing link? Of course, the two are interdependent and indispensable. Design determines whether the mold can be "used", and manufacturing determines whether it can be "used well". The two need to work together to ultimately determine the high performance of the mold.

What are the advantages of designing a hidden gate for injection molds?1. Automatically cut off the gate to improve production efficiency.2. No obvious sprue marks, improving product aesthetics.3. Smooth mold filling reduces the occurrence of weld marks.4. The gate and runner are designed inside the mold to improve the utilization rate of the mold cavity.

When making molds, don’t blindly pursue high-precision molds, as the processing cost is high and the cycle is long. For products that do not require high precision, setting the precision according to the requirements is the most efficient choice!

We have lost some customers because of the price, but we have won the trust and recommendation of more customers because of the quality. When making molds, we don’t want to rush blindly, but want to take steady steps. I always believe that genuine products and reasonable prices can lead to steady and long-term development.

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.

This is a plastic mold in our factory. After processing, it becomes a plastic product. After the video is posted, it becomes an advertisement. I post daily videos of the factory to show you our persistence in quality and craftsmanship, so that you can think of such a reliable injection molding factory when you need it.

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.
