We have professional designers and engineers to design drawings for each customer. Select high quality materials, after finishing and heat treatment, to produce high-quality mold. We also have a unique mold installation design, which can provide professional guidance in the easily damaged parts and select the most suitable mold. Reduce costs while minimizing strain.
Tube Roller Process
Raw material - sawing material - rough processing - Drilling - fine finishing - roller polishing - Typing Code - semi-finished product inspection - heat treatment - grinding hole - horizontal die cutting KEYWAY - quality inspection - oil cleaning - packaging
Heat treatment way:
There are four heat treatment way for your choose.
(1) Vacuum Heat Treatment :HRC 61-63
(2) Black treatment: HRC61-63
(3) Nit riding treatment: HRC61-63
(4) Vacuum Gas Quenching and Subzero Heat Treatment:HRC63-65
Warm reminding: Tube diameter≥133mm, HRC:58-61
Different heat treatment way , different price!
Tube Roller Packing:
1.Rust proof oil should be added to the export tube roller mould before removing the stains.
2.Packing in wooden boxes, lined with paper and cloth , to avoid bruising ,then use shockproof membrane.
3.The most outboard wooden packing , all the goods shipped by sea require fumigation wooden boxes.
