Pultrusion machine · Double-line rock-bolt configuration
FRP rock bolt production line
Henan Zhongsheng lists a two-line FRP rock bolt production line with separate winding and caterpillar pulling arrangements. Machine selection should address thread geometry, resin cure and handling of the finished bolt. Equipment ratings do not certify a bolt for mining or structural use.

Specify the mating interface
Include nuts, plates and any other mating parts in the drawing review. Confirm which parts and assembly operations are in the equipment scope.
Separate machine and product tests
A successful FAT does not establish suitability for a mine or structure. Assign product qualification and traceable sample testing separately.
Review the configuration with engineering before the quotation is finalized.

Production workflow
Review the line, stage by stage
Use these stages to define responsibilities, interfaces and the evidence needed at handover.
- 01
Prepare the feed
Agree reinforcement and resin preparation for the required bolt sizes.
- 02
Form the thread
Review winding tooling and the method of controlling thread geometry.
- 03
Cure and pull
Trial both paths with the selected materials and settings.
- 04
Cut and inspect
Check bolt length, thread fit and sample identification before discharge.

FAQ
Questions buyers ask
- Is this the same as a straight rebar line?
- Thread requirements and winding configuration are central to this dedicated product. Compare the approved bolt drawing with the proposed equipment scope.
- Does the machine make a certified rock bolt?
- Machine purchase does not establish finished-bolt certification or structural suitability. Agree the applicable product test program with the responsible engineer and laboratory.
- Can I plan production at the maximum speed?
- The listed range describes traction speed. Request accepted output for the proposed bolt size, thread and material system.
