Complete Your Parts In-House — No Separate Vendor Needed
Beyond primary machining, Zhuocheng provides a full range of secondary operations to complete your parts. From threading and knurling to deburring, cleaning and marking — all coordinated under one ISO 9001 quality system.
Some operations are completed in-house; others are managed through qualified partners under our quality system.
External and internal threads via live tooling on Swiss CNC, turn-mill and CNC turning centers.
M, MF — standard metric coarse and fine threads.
UNC, UNF, UNEF — inch series coarse and fine threads.
British Standard Pipe — BSPP and BSPT thread forms.
National Pipe Thread — NPT and NPTF tapered threads.
Tr and ACME — lead screw and power transmission threads.
Non-standard and special-profile threads per drawing.
Permanent marking for LOGO, serial numbers, date codes and traceability — available on metal and plastic parts.
Permanent, high-contrast marking for LOGO and traceability codes.
Precision engraved markings on flat or curved surfaces.
Screen-printed LOGO and text on flat surfaces.
Chemical etching for fine markings and decorative patterns.
Pad-printed LOGO on curved or irregular surfaces.
Every part is delivered assembly-ready — deburred, cleaned, inspected and packaged.
All sharp edges, burrs and flash removed — safe for handling and assembly.
Ultrasonic cleaning and drying to remove contaminants, coolant and chips.
LOGO, serial numbers or traceability codes applied per drawing requirements.
Final dimensional and visual inspection completed and documented.
PE bags, bubble wrap, plastic trays and cartons — or custom packaging per request.
Parts delivered assembly-ready — no additional processing needed at your end.
Deburring, cleaning, basic polishing, threading, knurling, drilling, tapping, slotting, and all 5 marking methods (laser, CNC engraving, silk screen, etching, pad printing) are coordinated in-house. Anodizing, plating, coating and heat treatment are managed through qualified partners.
Yes. With live tooling on our Swiss and turn-mill centers, many secondary operations like threading, knurling and cross-drilling are completed in the same setup as turning — improving feature-to-feature accuracy.
Yes. Laser engraving is available for LOGO, serial numbers, date codes and traceability markings on both metal and plastic parts.
Yes. Ultrasonic cleaning and drying are standard processes for parts that require contaminant-free delivery.
Yes. Standard packaging includes PE bags, bubble wrap, plastic trays and cartons. Custom packaging with individual compartments, anti-scratch protection, rust prevention and vacuum packaging is also available.
