At Rapicast, we provide precision injection molding services designed to meet a wide range of customer needs — from standard plastic parts to complex, high-end components that require tight tolerances, exceptional strength, or detailed surface finishes. Whether you’re producing functional prototypes, pilot runs, or full-scale mass production, we offer the flexibility and expertise to bring your designs to life — consistently and reliably.
We understand that each project is unique. That’s why we support:
Small to large part sizes
Single- and multi-cavity molds
Standard grade to premium aesthetic and functional plastics
Low-volume trial runs to full-scale mass production
Whether you’re manufacturing consumer electronics, medical housings, or industrial enclosures, we adapt our tooling and processing approach to match your application, tolerance, material, and budget.
Clients submit 3D CAD files or 2D technical drawings along with part requirements (material, quantity, color, finish). Our team reviews for manufacturability and recommends any needed design optimizations.
We prepare a quotation covering mold cost, part unit cost, lead time, and material options. For new tooling, we begin mold design and fabrication, ensuring compatibility with our high-performance injection machines.
We conduct initial mold trials (T1 samples), inspect critical dimensions, surface finish, and functionality. Approved samples are sent to the client for final validation before mass production.
Upon approval, we begin full production using our D4000 high-tonnage injection machine and other systems. Each batch undergoes rigorous quality checks to ensure dimensional accuracy, cosmetic consistency, and part performance.
Finished parts are post-processed as required (e.g., trimming, printing, assembly, packaging) and securely shipped to the client using reliable global logistics solutions.
At the heart of our injection molding operations is the D4000 high-tonnage injection molding machine, a powerful system engineered to handle even the most demanding production tasks.
Key highlights from the D4000 specification:
Clamping force: 4000 kN – ensuring part stability and mold precision
Injection weight: Up to 61794g (depending on screw size) – perfect for large parts or multi-cavity molds
Injection pressure: Up to 3111 bar – delivering excellent material flow and surface finish
Max mold size: 2400 × 2000 mm – suitable for oversized and complex tooling
Advanced configurations: Compatible with automation, hot runner systems, ejector plates, and more
Customizable: 4 screw configurations, variable L/D ratios, and fast response injection speeds up to 1279 mm/s
With this level of performance, we can produce large, multi-functional, or geometrically complex items while maintaining dimensional accuracy, cosmetic quality, and repeatability — ideal for industries that demand uncompromising precision.
We support a wide range of thermoplastics including:
ABS, PC, PA (nylon), POM, PBT, PP, TPU
Glass-filled materials, flame-retardant grades, UV-resistant plastics
Color matching, texture customization, overmolding, and insert molding available
Post-processing: pad printing, ultrasonic welding, coating, and packaging
✅ Flexible production capacity – from pilot to high-volume
✅ Support for complex tooling & part geometries
✅ In-house engineering & mold validation
✅ High tonnage, high-precision equipment
✅ Fast turnaround with strict quality assurance
