06 Why Weida

Why Choose Weida

A low-temperature physical grinding route that mills even the most difficult composite scraps into reusable material.

01

Low-temperature Grinding

Material-on-material, blade-free to avoid fiber tangling; liquid-cooled chamber protects material properties.

Your Pain

High-temperature grinding damages fiber performance; blades wear fast and jam.

02

Wide Output Range

From 10mm short fiber to 400 mesh powder with low-speed high-torque motors and adjustable fineness.

Your Pain

Different materials need different fineness; narrow-range machines require multiple units.

03

24-hour Continuous Run

Fully enclosed chamber and low-speed low-wear design support continuous production and stable output.

Your Pain

Frequent manual attendance and cleaning stops cut output.

04

Multi-material Adaptability

Carbon fiber, glass fiber, FRP, aramid, basalt, EVA/PET/PE and 14+ more materials trial-verified.

Your Pain

Composite materials vary widely; generic machines adapt poorly.

05

Verify Before Buying

Sample trials confirm output specification and capacity before you move to business.

Your Pain

A wrong machine cannot be returned — money wasted.

07 Material Cases

Material Trial Showcase

Built on years of real trial-machine accumulation across multiple composites and scrap types — no data dumps here, just the conclusion: whatever your material, we have a ready answer.

Before milling carbon fiber, know which one you have

Even within “carbon fiber”, tow size, resin content and fiber orientation noticeably change the milling result.

10 FAQ

Frequently Asked Questions

Carbon fiber, glass fiber, FRP, aramid, basalt, EVA/PET/PE and more can all be handled — a sample trial is recommended to confirm output and capacity.

Output ranges from 10mm short fiber to 400 mesh powder, with adjustable fineness.

Yes. Send a material sample to our Zhanjiang factory; we issue a particle analysis and capacity report after the trial.

Material-on-material, blade-free avoids fiber tangling; liquid cooling protects material properties — ideal for high-performance composites like carbon fiber.

Yes. Fully enclosed chamber and low-speed low-wear design support continuous production and stable output.

Single machines 45–60 days; complete lines 60–90 days, subject to configuration and schedule.
