Equipment Highlights & Process Advantages
It’s not just about “having equipment,” but knowing how to use it to solve customers’ manufacturing challenges.
Vacuum Compression Strength for Both Giant and Precision Parts
We have nearly 20 unitshigh-end vacuum rubber molding machines, with tonnage from 200 tons up to a rare 1200 tonsgiant machines (platen up to 1900×1600mm). A powerful vacuum system fully resolves air-trap and short-shot issues in complex or double-layer products, perfectly handling everything from tiny precision parts to oversized rubber components.
Energy-Saving, Eco-Friendly Advanced Cold-Runner Injection
The plant has over 10 units 200T–300T high-end cold-runner rubber injection machines. Precise temperature control achieves flash-free or near-flash-free production, supporting sustainability while greatly reducing high-cost material waste and improving dimensional stability and yield.
Dedicated Rubber/Silicone Separation & High-Purity Control
Dedicated 300T rubber and 300T silicone injection machine groups fully separate materials and equipment of different properties. Strict material segregation effectively eliminates cross-contamination risk, maximizing the purity of silicone products (such asmedical-grade, food-grade parts).
Beyond Single Materials: Composite Process Integration
The line also features high-end German plastic injection machines and dedicated PU pouring equipment for cross-material integration, completing rubber/silicone-to-rigid-plastic bonding in-house (two-shot over-molding)” and “PU foam pouring” composite molding, saving customers the cost of cross-plant outsourcing.
One-Stop In-House
From Mold Development to High-Precision Production, All in One Stop
Unlike peers that rely on outsourcing, Sanhao Rubber keeps all key processes in-house, controlling every link of quality and lead time.
Equipment Is Strength; Scale Is Trust
Our complete manufacturing chain — an in-house tooling department plus diverse molding lines — flows seamlessly from product-drawing review and mold design/development to trial-mold revision and mass production, greatly shortening the development cycle and responding with maximum efficiency to design changes or mold repairs.
- From Giant to Precision, Fully Covered: Vacuum compression tonnage 200T–1200T, handling both oversized components and tiny precision parts.
- Multi-Material Integration: Rubber, silicone, cold-runner, plastic injection and PU pouring — all in one place.
- In-House Mold Making: High-speed machining centers and EDM equipment complete the work in-house, saving the time cost of cross-plant outsourcing.
