- Surface treatment, inspection, packing and loading coordination.
Manufacturing flow
From raw material review to export packing
The exact route depends on the product standard, size, material, grade, finish, quantity and documentation requirements.
Thread Rolling
Full-thread, partial-thread and specified thread-length production.
Heat Treatment
Applied according to the approved material and mechanical grade requirements.
Surface Treatment
Options include black, zinc plating, hot-dip galvanizing, Dacromet and PTFE coating where applicable.
Warehouse & Order Staging
Core products and prepared orders are organized before packing and shipment.
Export Packing
Cartons, bags, pallets or wooden cases are selected according to product size and transport conditions.
Core manufacturing focus
Built for heavy-duty and project-specific fasteners
Large Diameter
Large and special diameters are reviewed against drawings, standards and order requirements before quotation.
Extra Long
Long-length requirements and specified thread lengths are reviewed against the approved product specification and process route.
Strength Grades
Strength grade requirements are reviewed together with the product standard, material and heat-treatment route.
Custom Production
Special heads, bent parts, studs, anchors and machined threaded components can be reviewed from drawings.
Custom-order review
What the factory checks before accepting a non-standard order
A custom order is not accepted on size alone. The complete process route and inspection basis must also be practical.
Drawing Review
Dimensions, tolerances, thread form, head geometry and application requirements.
Process Review
Material, forming, machining, thread rolling, heat treatment and coating route.
Inspection Plan
Dimensional checks plus any required hardness or mechanical test arrangements and documents.
Packing Plan
Labels, rust protection, palletization, matched parts and shipment handling.
