Quality Mold = Quality Product
A reliable mold is the foundation of a great product. At Rayleap, our in-house tooling experts ensure every mold is built to last — minimizing downtime, optimizing cycle time, and producing parts with consistent accuracy from first shot to mass production.
Our Proven Mold-Making Process (From Design to Delivery)
Rayleap Plastic Inc, provide high-precision injection molds for your plastic parts manufacturing. Whether it’s single-cavity molds or multi-cavity molds, we can customize them to meet your specific requirements.
Moldflow analysis
We simulate mold flow early in design to avoid defects like sink marks, weld lines, and short shots — saving you time and money.
CNC Process
Our high-precision CNC machines shape mold components with tight tolerances, ensuring optimal mold fit and function.
Wire EDM Cutting
For intricate cores, inserts, and sharp corners, we use EDM technology for ultra-fine detail and flawless finishes.
Grinding process
We employ precision grinding to achieve the desired surface finish and tight tolerances on mold components. Grinding ensures that every detail meets the exact specifications for optimal mold functionality.
Mold Surface Finish
We pay meticulous attention to the surface finish of the mold. A high-quality surface finish is essential for product release, aesthetics, and functionality. Our finishing processes ensure that your mold meets the highest industry standards.
Mold assembly
In this critical stage, we meticulously assemble the various components of the mold, ensuring that every part fits seamlessly. Proper assembly is key to the mold's functionality and longevity.

What Affects Injection Mold Cost? Plan Smarter With These 6 Key Factors
Intricate geometries, deep undercuts, or sharp corners require more advanced tooling and extra machining — increasing mold cost. We help optimize design for manufacturability.
More cavities mean more parts per cycle but a higher upfront mold investment. Fewer cavities cost less upfront but reduce output. We'll help you choose the right balance.
Larger parts need bigger molds, more steel, and larger molding machines, which drives up production costs. Compact part designs can reduce cost.
Custom surface finishes, textures, inserts, sliders, or special post-processing like pad printing or laser marking can all raise total tooling and production costs.
Choosing P20, H13, or S136 impacts mold life, machining time, and polishing capability. High-grade steel lasts longer but costs more upfront.
The faster a part can be molded, cooled, and ejected, the lower your per-part cost. Part design and mold cooling systems both affect this metric
