Advanced Fiber Reinforced Composite Manufacturing Solutions

Zhejiang Henghui Machinery Co., Ltd offers a variety of high-end options for composite manufacturing.

The first RIM processes serve for accurate metering and mixing and are accompanied by added fillers. SCS serves for lightweight and high-strength components from fibre honeycomb panels, and FCS provides a flexible solution for low-volume production.

In LFI, continuous fibre is combined with PU in a system with high impregnation efficiency. In high-pressure RTM, it is possible to mould a resin without bubbles, which provides a high level of strength.

In addition to these technologies, there are also some production lines in support, such as the Glass Fibre Reinforced Polyurethane Foam system used for LNG insulations and the Large-Scale Composite Profile Extrusion line aimed at lightweight and high-durability industrial profiles.

These modern, precision, and efficient manufacturing technologies are aimed at contemporary manufacturing.

RRIM Reinforced Reaction Injection Molding

RRIM - Reinforced Reaction Injection Molding
Henghui-machinery
Zhejiang, China
OEM Manufacturer
The RRIM (Reinforced Reaction Injection Moulding) System is awarded efficiency, flexibility, and precision. This process incorporates servo/hydraulic pistons to metered control polyol and isocyanate, controlled by speed via servo-hydraulics. Injection of short fibres (e.g., glass fibre, carbon fibre) or fillers (e.g., calcium carbonate, barium sulphate) into a closed mould is used to pour a material system, creating high-quality results for various applications.
Precise metering with servo/hydraulic-driven piston.
Durable, high-speed wear-resistant mixing head.
Supports short fibers and fillers.
Continuous feeding for low pouring volumes.
Produces thin-walled, dimensionally stable parts.
