Shrinkage is nightmare of every injection molding engineer, but what causes them? 1: The Material Itself: Materials like PP/PE/PA have high shrinkage rates and poor flow ability, making them prone to shrinkage.2:Poor Product Design: Uneven wall thickness, unreasonable design of reinforcing ribs, pillars, and other localized protrusions. 3:Injection parameters:Insufficient holding pressure, improper temperature control, and inability to continuously supply material to the cavity; 4:Mold design: Incorrect gate location, uneven distribution of the cooling system.;What other product defects are causing you headaches?

You think traders are the “easy” choice? Think again. As a injection mold factory, we handle everything: design drawings, mold manufacturing, production, QA, even logistics. Means you don't need to communicate back and forth. You get factory pricing and fast responses. One stop, zero hassle.

Complex geometry? Special materials? Think it's a challenge? For us, it's another day at GV MOLD. The successful mold trial of this noise collector proves our professionalism. 4 plastic parts in one injection mold, different structure and different material. We believe in fair pricing and excellent quality. Because impressing customers isn't about hype—it's about reliability.

Think Non-Standard parts Are a Nightmare to Make? Check out this custom gearbox housing we built for a client. PPA+35% glass fiber injection molding, heat-resistant and impact-proof. Mold tolerances? We controlled them tight, so gears spin smooth, no jams.We turn tricky custom jobs into reliable parts.

At GV MOLD, How to achieve efficiency and quality simultaneously? The answer: seamless automation. The hopper picks up raw materials, after a series of operations, the mold opens, and a robotic arm extends into the cavity to grab the molded part. The product is sent to the conveyor belt, where workers inspect each product. This combination of Precise Execution and Continuous Operation doesn't just boost efficiency, it guarantees product stability.

Tens of Thousands for Machines, Pennies for Parts. In low-margin times, Mold Value Is Everything! 3C digital parts? Small home appliances? Mechanical components?Simple molds? We nail ’em. Complex structures? No sweat. First class quality and reliable service to ensure smooth operation of your production line

For Bluetooth headset shells, you can’t pick “fast” or “precise”—you need both. We use a 1+1 mold structure—that’s 10% faster injection than standard single-cavity molds. We nail tight tolerances and perfect mold matching, no visible parting lines on your shells. Speed without cutting corners. Precision without dragging your timeline.
