In-House Core Processes
Critical Manufacturing Steps Under Direct Control
PremFixer completes the key processes that determine bicycle-level assembly precision and repeatable batch production inside the factory.
Explore Production EquipmentCold Forging & Cold Heading
Multi-station forming supports repeatable production of standard and custom fasteners while preserving formed material flow around the part geometry.
CNC Precision Turning & Milling
CNC lathes and vertical machining centers produce special bolts, pivot axles, hangers, sleeves, spacers, and complex custom parts, with tolerance targets confirmed during drawing review.
Rolled Thread Formation
Rolled threads are selected according to material, thread class, application, and approved drawing requirements, with thread fit verified through the project inspection plan.
Controlled Heat Treatment
Heat-treatment targets are defined by material grade, strength requirement, application, and the approved project specification.
Inspection & Traceability
Quality Evidence for Every Production Batch
Inspection follows the approved drawing, application requirements, and batch-specific control plan, with documentation prepared for the parts you receive.
- Dimensional control
- Coordinate measurement and project-specific critical-dimension verification.
- Thread verification
- Go/no-go thread inspection according to the approved batch control plan.

From Drawing Approval to Repeatable Batch Production
An approved drawing becomes a controlled production baseline only after sample and first-article approval. Repeat orders then follow the same route, checks, finish, and packing record.
Lock the Specification
Drawing, application, material, tolerance stack, thread fit, finish, quantity, and packing requirements are reviewed together.
- Control Focus
- Critical dimensions, bearing interfaces, under-head geometry, torque surfaces, and corrosion target.
- Output
- Confirmed specification, process route, and CTQ inspection plan.
Approve the First Article
Tooling or CNC programming, sample production, fit checks, and first-article inspection are completed before release.
Batch Release Rule
No batch production before your sample approval.
- Output
- Approved sample package and released manufacturing baseline.
Run Repeatable Batches
Production, finishing, in-process checks, final inspection, packaging, and shipment follow the approved baseline.
- Control Focus
- Lot identity, process checkpoints, finish compliance, dimensional release, and packing traceability.
- Output
- Inspection pack, traceable lot records, and coordinated shipment.
Repeat Order Baseline
