Hot runner molds are recommended in these four situations to save money! 1. Annual production capacity exceeds 100,000 pieces, saving significant runner material costs; 2. Medical precision parts, no gate marks, and stable pressure; 3. Transparent parts such as lenses and water cups, avoiding sink marks at the gate; 4. Thickness < 1mm, good melt fluidity, and no short shot.

Like this kind of plastic parts, this one, This one... No matter what type of plastic parts, GVMOLD can achieve high precision, good fitting, and solid materials. From appearance to performance, every detail can stand the test.

Should high-precision molds use hot runners or cold runners? If it is long-term mass production with high raw material costs and a pursuit of high efficiency, hot runners are more suitable. But if it is a small-scale trial production and the product structure is simple, the cold runner is fully capable. The core depends on three key factors: production demand, cost, and product characteristics

Whether it is a mold with a simple structure or a complex one, whether you’re using standard injection materials or special ones, we’ve got you covered. We can break through traditional mold design thinking and accurately control every detail in the machining process. Our goal is to team up with you and turn “this can’t be done” into “we did it right.”

We deliver not only molds, but also the market competitiveness of your products! From optimizing mold design to reducing trial mold losses, to adjusting injection molding processes to minimize defects and improve precision in plastic parts, every step is helping you improve quality and reduce costs.

Wondering how to improve product quality?High quality doesn't just come from final inspection. It's about controlling every step of production: mold flow analysis to anticipate problems, precision equipment to maintain mold accuracy, and selecting raw materials that meet standards.Nailing the entire process, that’s how you get consistent, top-tier quality every time.

What is the most important thing in an injection mold factory? Someone said: If you spend money on high-end devices, you win! Someone said: Price reduction to grab orders is the real thing! In fact, accuracy is the foundation of success! Quality is the core of turning back! Only by firmly grasping both can the factory persist in the long run!

The mass production of router housings is just in time, with dual online production capabilities and high quality! Our 1+1 mold design and the surface texture of products are highly recognized by our customers. We specialize in producing molds for all types of plastic housings, not just router housings.

Need to make molds and plastic products? "Fast, accurate, and stable" are the basic requirements. Or a technical hardcore—accuracy and efficiency are guaranteed. Or strong clientele—binding with high-value-added companies like medical and automotive.Or higher cost-effectiveness—helping customers reduce costs and increase efficiency!

Why is mold design so crucial in mold manufacturing? 1. Cost: A single flawed design can cost more to modify than a new mold! 2. Efficiency: Lack of space for a robot requires hiring three more people, while poor cooling design can cut production capacity in half. 3. Quality: Uneven wall thickness, cracking, incorrect parting patterns, and flash—90% of defective products are caused by design.

There's a misconception in the mold industry: Many people believe mold cost is determined by mold size. In reality, a palm-sized precision mold, while requiring minimal material, can cost more than a taller rough mold when machined to micron-level precision. Structural complexity, material quality, and precision requirements are the key factors influencing cost.

Does a simpler mold parting save money? A single parting surface reduces parts, lowering processing costs. However, if the product has undercuts or side holes, forced simplification can increase secondary processing costs. While simple parting offers significant advantages for small batches, large-scale production can actually lead to higher long-term costs.
