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.

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.

Want to implement a creative product? You can’t do without solid structural design. Your product needs someone who understands the ingenuity of appearance and the

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.

Do you know the depth of the venting groove of the injection mold? The depth of the venting groove is the key to balancing "gas discharge" and "preventing overflow". For general plastics such as PP and ABS, the depth is generally 0.02 to 0.04 millimeters. For engineering plastics such as PC and POM, the depth is generally 0.01 to 0.02 millimeters, and for thermosetting plastics, the depth is more than 0.07 millimeters. If the depth exceeds the limit, flash will occur, and if it is too shallow, air will be trapped.

GV Mold’s hot runner molds are a game-changer! Customers rave about their precision, “ensuring stable product dimensions and high quality every time.” They precisely control injection temperature. “Simplifying the mold structure without cold slug wells saves us money,” notes one client. Production efficiency soars, and less waste means it’s “both eco-friendly and economical – our ideal choice!”

In the injection molding production process, surface defects, dimensional deviations, and problems are common, and about 80% of these problems are caused by mold design or manufacturing defects. Our factory's engineering team has an average of more than 10 years of industry experience and can quickly diagnose and solve various problems, from mold flow analysis to mold optimization, from material selection to process adjustment, providing comprehensive solutions to ensure that products are both beautiful and practical
