Precise mold fitting leaves no gap for plastic to escape. Accurate process control delivers the right pressure, at the right time, nowhere else. The result? Products with burr? Not at all.

This isn't just about being smooth. It's about defining the standard. We don't just polish a mold; we engineer the surface finish into the steel itself. The result? Every single shot meets your spec. Perfectly. Consistently.

This is GV’s new beginning. Where every innovation is measured by its intelligence and its integrity to the planet. We are ready. Ready to build, ready to innovate, ready to lead with responsibility.

simplified injection mold making process


Design & Engineering: Design the mold based on the product's 3D model, planning how it will split open, eject parts, and be cooled.



Machining & Manufacturing: Use machine tools like CNC and EDM to create the core mold components (core and cavity).



Polishing & Assembly: Polish the machined parts to the required surface finish, then assemble them into a complete mold.



Mold Trial & Debugging: Install the mold in an injection molding machine for testing.



Mass Production: Once debugging is complete, the mold is ready for mass production of plastic parts.

Improper mold polishing affect the product's appearance. Precise matching is key to avoiding pitfalls. A3 Level: Feels like fine sandpaper, only for hidden, internal parts. A2 Level: Matte finish with no obvious texture, suitable for ordinary visible parts. A1 Level: Near-mirror effect, essential for transparent parts. A1 Level: Ultra-mirror level, best for High-gloss parts.

The precision of molds is crucial to the life of products. Take a look at our “Precision Inspection Dream Team”—we leave zero room for error: CMM: Scans complex mold dimensions with micron-level accuracy. Profile Projector: No hidden flaw, scratch, or mismatch slips through our checks. Hardness Tester: Proving the steel’s soul can take a million hits. You think we’re being too fussy with mold precision?

Still complaining about mold price? Mercedes and BMW aren’t cheap, yet more and more people choose them. Nobody drinks free river water, and everyone knows a $5 diamond is fake. What you're REALLY buying:Qualified accuracy. Long life. Stable mass production. These will reduce your hidden costs and allow you to achieve a substantial profit.

Want to nail mass production with zero headaches? Start with choosing the right mold, but what is the core of quality? Ask 3 mold experts, get 3 different answers. Designer: PRECISION! If the dimensions are off by microns, the whole product fails. Programmer: Stability! No random glitches, just consistent runs. Fitter: Lifespan! Molds that keep up with high-volume demands. Who’s right?”

Mold misalignment and wearing out fast , product flash? The culprit is almost always bad parallelism! Precision isn't a guess. It's a measured fact. We run a dial indicator across the mold surface. Only when the needle doesn’t budge an inch do we sign off on it.

Are you still troubled by mold wear and Constant Production Halts? We’ve cracked the code for long-lasting molds, triple protection: Use high-quality steel as the base, then nitriding to enhance hardness, and finally a special coating for wear and corrosion resistance. This triple protection locks in durability! It can reliably withstand high production volumes!

In the world of microns, where machines reach their limit, another intelligence takes over. Look at these hands—calloused, but steady as a rock—hand-polishing the mold to its final, perfect finish. You think precision molds depend only on machines? But master craftsmen handle the details machines can’t replace.

Stuck choosing between cheap, fast, or good? That’s the oldest trick in the book. The truth is: a professional mold factory must achieve a balance among the three. ✅ Transparent costs. ✅Quality Steel. ✅Controllable Timeline. A great mold isn’t about one shining advantage. So tell me, which one are you MOST often forced to sacrifice?
