HTsin Core Technical Strengths in Automotive /EV Manufacturing
Engineering Excellence for Extreme Environments
01
Precision Machining Technologies
In automotive/EV manufacturing, precision defines performance and safety. HTsin machines powertrain components (motor housings, gear shafts) and lightweight chassis parts via 5-axis machining centers (24,000r/min) and high-speed milling, achieving ±0.005mm accuracy (IATF 16949 compliant). R&D projects like “High-Efficiency Cutting for Aluminum Alloys” optimize CNC processes for mass production consistency.
02
Material Application and Innovation
To support electric vehicle performance, range, and durability, Htsin specializes in the precision manufacturing of industry-proven materials. We expertly process:
High-Strength Aluminum Alloys (e.g., 6061-T6)
Lightweight Magnesium Alloys (e.g., AZ91D)
Heat-Resistant & Structural Steels
03
Advanced Manufacturing Processes
Htsin combines die casting, forging, and post-processing for complex automotive parts. For EV motor rotors: die casting (±0.01mm tolerance) → 5-axis machining (Ra≤0.8μm) → insulation coating—ensuring high rotational stability. Near-net-shape manufacturing reduces waste and lead times, optimizing cost-effectiveness for prototypes and mass production.
Precision in Every Step
End-to-End Process Control for Reliable Component Production
Engineering
Our engineering team leverages advanced CAM and manufacturing analysis to transform your designs into optimized production plans. We focus on creating efficient machining processes that ensure precision, reduce costs, and shorten lead times.
Stringent Material Screening
Source global premium materials (alloys, composites, biocompatibles) and conduct strict inspections via spectrometers, metallographic microscopes, and material testers. This ensures materials meet industry-specific standards (e.g., AS9100, ISO 13485) and perform reliably in target environments.
Precision Machining
Combine multi-process collaboration (cutting, casting, forging, additive manufacturing) with advanced equipment (5-axis machining centers, high-speed mills) to achieve tight-tolerance production—suitable for ultra-precise robotics parts, semiconductor components, or heavy industrial machinery.
Surface Treatment
Specialized workshops deliver tailored surface processes (anodizing, plating, heat-resistant coating) with strict process control. Enhance wear resistance, corrosion protection, or biocompatibility—critical for automotive EV parts, medical implants, or oil & gas equipment.
Assembly and Debugging
Use laser measuring tools for high-precision component assembly, paired with real-condition testing (e.g., load, temperature, vibration) to verify performance stability. Ideal for robotics joints, aerospace systems, or industrial automation assemblies.
Full-Process Quality Inspection
Implement a comprehensive traceability system with advanced testing: coordinate measuring machines (CMM), non-destructive testing (NDT), and dimensional checks. Ensure compliance with global industry standards (IATF 16949, API) across prototypes, small batches, and mass production.
