Production Capacity & Quality Assurance

Our injection molding workshop is built for real production capacity—no exaggeration.

We operate:

22 injection molding machines

5 compression molding presses

20 auxiliary units

Annual output:

15 million pieces of nylon and polyester products

100,000 sets of rail power supply protection products

500,000 sets of vibration and noise damping products

This covers insulated rail gauge blocks, fastener components, and transit protection systems. No vague claims—just numbers that prove we can handle bulk orders and tight deadlines.

CNAS-Accredited In-House Testing Center

All incoming raw materials and finished Insulated Bushings undergo thorough physical and chemical performance testing at our CNAS-accredited testing center. Tests cover insulation resistance, hardness, shear strength, impact resistance, water absorption, and more.

We perform testing both before production and prior to shipment. This two-step process ensures full compliance with standards and guarantees that every component of our track rail fastening system accessories meets the precise requirements of your rail line.
