Sheet Metal Chassis Welding & Assembly for Industrial Machinery

　　When industrial machinery operates under heavy loads, constant vibration, and harsh workshop conditions—its chassis isn’t just a frame: it’s the backbone of reliability. Our specialized welding and assembly services deliver sheet metal chassis built to meet the toughest industrial demands, with precision tailored to your machinery’s unique needs.

　　1. Welding: Strength Engineered for Industrial Durability

　　We prioritize weld integrity to ensure chassis withstand the rigors of industrial use, with material-specific techniques and strict quality controls:

　　Material-Matched Welding Processes:

　　MIG welding for carbon steel (A36/S45C) chassis (ideal for heavy-duty machinery like excavators or loaders) – delivers high deposition rates and strong, impact-resistant joints.

　　TIG welding for stainless steel (304/316) chassis (critical for food processing or chemical machinery) – creates clean, seamless welds that resist corrosion and contamination.

　　Pulsed MIG welding for aluminum (6061-T6) chassis (used in lightweight automation equipment) – minimizes heat distortion while maintaining structural strength.

　　Industry-Standard Compliance: All welds adhere to AWS D1.1 (structural steel) and AWS D1.2 (aluminum) standards, with 100% visual inspection and optional ultrasonic testing (UT) for high-criticality chassis (e.g., mining machinery).

　　Anti-Distortion Solutions: Pre-heating for thick-gauge sheets (≥10mm), post-weld stress relief (PWSR) for vibration-prone applications, and fixture-based welding to keep chassis dimensions stable.

　　2. Assembly: Precision Aligned for Machinery Compatibility

　　Industrial machinery relies on chassis that integrate seamlessly with motors, hydraulic systems, and control panels. Our assembly process ensures zero misalignment and maximum usability:

　　Micron-Level Precision:

　　CNC-aided positioning for mounting holes (tolerance ±0.05mm) to fit motors, gearboxes, and sensors.

　　Laser calibration for chassis squareness (max deviation ≤0.3mm/m) – prevents premature wear on moving parts like conveyor belts or robotic arms.

　　Component Pre-Integration:

　　Pre-assembly of hinges, access panels, and cable management channels to simplify on-site installation.

　　Test-fitting with critical machinery parts (e.g., hydraulic cylinders, drive shafts) to eliminate assembly delays.

　　Quality Traceability: Every chassis includes a detailed report covering material certificates (MTRs), weld inspection records, and dimensional test data – compliant with ISO 9001:2015 and CE industrial standards.

　　3. Custom Solutions for Every Industrial Sector

　　We don’t just build chassis—we engineer them to fit your machinery’s unique operating environment:

　　Heavy-Duty Machinery: Reinforced chassis for construction equipment (excavators, bulldozers) with welded gussets and thickened steel plates (12–20mm) to handle 500+ kg static loads.

　　Automation & Robotics: Lightweight yet rigid aluminum chassis for conveyor systems and robotic workcells – optimized for space efficiency with precision cutouts for sensors and actuators.

　　Process Equipment: Corrosion-resistant stainless steel chassis for chemical mixers, food packaging machines, and pharmaceutical equipment – featuring seamless welds to avoid product contamination.

　　Retrofit & Upgrade: Custom chassis modifications for aging machinery (e.g., adding mounting rails for new control panels, reinforcing frames for increased load capacity) to extend equipment lifespan.

　　4. End-to-End Support for Your Production Cycle

　　Beyond welding and assembly, we streamline your workflow with value-added services:

　　DFM (Design for Manufacturability) Reviews: Our engineers optimize your chassis design to reduce weld complexity, improve assembly efficiency, and lower production costs – no extra fees.

　　Surface Protection: Post-assembly treatments tailored to industrial environments:

　　Powder coating (epoxy/polyester) for scratch resistance and chemical protection (ideal for workshop machinery).

　　Hot-dip galvanizing for outdoor or high-moisture applications (e.g., agricultural machinery, mining equipment).

　　Flexible Production & Delivery:

　　Low-volume prototypes (3–5 units) for machinery R&D – ready in 1–2 weeks.

　　High-volume batches (100+ units) for mass-produced equipment – with consistent quality and on-time delivery (98% on-time rate).

　　Partner for Chassis That Power Your Machinery’s Performance

　　Your industrial machinery deserves a chassis that doesn’t just “hold up” – but enhances its reliability, safety, and lifespan. Our welding and assembly team combines decades of industrial experience with advanced equipment to deliver solutions that meet your exact specs.
