Engineering summary of custom CRS dustproof metal case and sealed electronic enclosure fabrication by FIWOK METALWORKS. Operating from our Shenzhen facility with 14+ years of industrial trade experience, we specialize in high-precision fiber laser cutting, multi-axis CNC bending, and reinforced TIG/MIG welding for sensitive electronic boxes, sensor shields, and protective industrial equipment chassis. Utilizing cold rolled steel substrates paired with impact-resistant matte black powder coated finishes, we deliver robust environmental sealing across flexible small-to-medium batch sizes (10 to 10,000+ pieces). Our workshop manages drawing-based linear tolerance control down to ±0.05mm for laser-cut holes and ±0.15mm for synchronized bending based strictly on blueprint requirements. All parts feature 100% material source traceability and inspection reports.
FIWOK METALWORKS offers custom CRS dustproof metal cases with high-durability powder coating. Expert laser cutting, CNC bending, and welding services for industrial and electronic enclosures holding ±0.05mm positioning with 24h DFM.

Production FAQ
Q1: How does FIWOK ensure the dustproof integrity of the CRS metal case?
A: We utilize precision TIG/MIG welding for all critical joints and edges. After welding, each case is checked for structural gaps to ensure that when paired with gaskets, the final enclosure meets industrial dust-sealing requirements.
Q2: What is the benefit of matte black powder coating for CRS equipment shells?
A: Powder coating provides a much thicker protective layer than wet paint, preventing the CRS substrate from oxidation. The matte finish reduces light reflection and provides a high-end industrial aesthetic for sensors and electronic modules.
Q3: How do you maintain consistent dimensions for batch orders of 10,000 units?
A: We use synchronized CNC bending with real-time pressure sensors that compensate for material thickness variations. This ensures that every part in a large-scale production run maintains a consistent +/-0.15mm tolerance.
Q4: Can you customize interface cutouts for different sensor cable glands?
A: Yes. Utilizing fiber laser cutting, we can produce burr-free, custom-shaped apertures for various connector types. This flexibility allows us to serve the 10-10,000 unit SME market without the need for expensive hard tooling.
Q5: Is there a cost advantage for long-term recurring supply of 5,000+ units?
A: Absolutely. Recurring batch manufacturing allows us to implement lean production cycles and volume material sourcing, passing the maximum price reduction per unit directly to your supply chain.
