Industrial-Grade Manufacturing Process Control

To guarantee zero-defect delivery, every Ruixin rack undergoes a standardized, traceable production loop:

Step 1: Premium Material Selection

We source certified high-grade alloy steels including C45 (1.0503), 42CrMo4 (1.7225), and S45C to ensure uniform core strength.

Step 2: CNC Rough Machining

High-speed CNC milling machines pre-cut the teeth profiles and drill mounting holes while leaving precise grinding allowances.

Step 3: Advanced Heat Treatment

Laser or high-frequency induction hardening is applied to teeth surfaces to achieve HRC 50–55, optimizing wear resistance without making the core brittle.

Step 4: Precision Teeth Profile Grinding

Using elite CNC rack grinding machines to correct any thermal distortion from heat treatment, ensuring exact pitch and pressure angle.

Step 5: DIN-Level Quality Inspection

Every batch is subjected to coordinate measuring machine (CMM) testing for pitch accuracy, straightness, and surface roughness.

Step 6: Anti-Corrosion Treatment & Traceability

Racks undergo black oxide, phosphating, or chemical anti-rust coating. Laser-etched batch codes are applied for lifetime tracking.

Packaging & Global Secure Delivery

Industrial gear components require rigorous protection during maritime and air transit to avoid moisture damage or physical impacts:

Stage 1: Thorough chemical cleaning followed by a heavy coat of premium anti-rust oil.

Stage 2: Dual-layer vacuum plastic sealing to completely lock out oceanic moisture and salt air.

Stage 3: Heavy-duty, ISPM-15 compliant export wooden cases fitted with shock-absorbing foam inserts.

Logistics Options: Sea freight (FCL/LCL), Air cargo, and Express (DHL/FedEx/UPS) with full tracking documentation.
