FAQ

  1. Equipment and Processing Capabilities

  • What are the cutting and bending precision levels of various machines?
    • Germany Trumpf TruLaser 6000W Fiber Laser Cutting Machine: Cutting thickness: 0.1mm–25mm (Cutting precision: 0.03mm–0.20mm).
    • Canada Accurpress Press Brakes: 100 tons, 2.5m; 250 tons, 3.3m; 320 tons, 4m. Bending precision: 0.2mm/m.
  • What is the maximum sheet size and thickness each laser cutting machine can handle?
    • Germany Trumpf TruLaser 6000W Fiber Laser Cutting Machine: Worktable size: 2m x 4m.
      • Maximum cutting thickness:
        • Iron plate: 25mm
        • Aluminum plate: 20mm
        • Copper plate: 8mm
  • Can the factory handle special material requirements, such as alloys or surface-treated metals?
    • Commonly sourced materials include:
      • Iron plates: Q235, Q345, Q355
      • Galvanized sheets: SGH340+75, SGH340+120, SGH340+275
      • Stainless steel: S304, S316
      • Aluminum and alloy plates: 6061, 5052, 5754, 5083
  • Are there technical limitations when cutting, welding, or bending complex shapes?
    • Generally, as long as the flatness of the sheet material meets the standards, cutting can proceed without issue. For complex shapes in welding or bending, prior communication is required to determine the processing plan before production.

  1. Materials

  • What types of metals and surface treatments can the factory process (e.g., stainless steel, aluminum, galvanized steel)?
    • Iron plates: Q235, Q345, Q355
    • Galvanized sheets: SGH340+75, SGH340+120, SGH340+275
    • Stainless steel: S304, S316
    • Aluminum and alloy plates: 6061, 5052, 5754, 5083
  • Can customer-supplied materials be processed?
    • Yes, customer-supplied materials can be processed, as long as they fall within the factory's processing capabilities.
  • Do the materials used meet international standards like ASTM or ISO?
    • All materials comply with Chinese product inspection standards and ISO certifications. (Material quality inspection reports issued by manufacturers are available, and further testing can be done through SGS Testing Services [Qingdao] Co., Ltd.)

  1. Production Process

  • What are the typical lead times for small and large orders?
    • Lead times for both small and large orders are determined through consultation with the customer.
  • What is the shortest lead time for urgent orders or rapid prototyping?
    • Shortest lead times for urgent orders depend on factors like product quantity and size and are determined through consultation. The principle is to ensure quality while meeting customer needs as much as possible.
  • Can the factory provide a clear production schedule and delivery plan at project initiation?
    • Yes, a production schedule and delivery plan can be provided before project initiation. (This is based on order quantity, processes involved, and other time factors, and finalized through customer consultation.)
  • What formats of CAD design files are accepted (e.g., DXF, DWG, STEP)?
    • The factory accepts all listed CAD file formats.
  • Does the factory provide CAD drafting services? If so, what is the process and cost?
    • CAD drafting services are available within reasonable capabilities. Costs depend on the complexity of the client's design and are determined through consultation.
  • Does the factory use nesting software to minimize material waste and reduce costs?
    • The Germany Trumpf TruLaser uses proprietary TruTops Boost nesting software to maximize material utilization and minimize costs for customers.
  • Can the factory handle batch production, and how is production progress tracked?
    • Yes, batch production is supported. Nesting software generates material layouts and theoretical processing times for each batch. Daily production plans are based on these times, and progress is tracked by production staff reporting daily outputs.

  1. Welding and Assembly

  • What welding technologies (e.g., MIG, TIG) are available?
    • Both MIG and TIG welding are supported (not conducted in-house).
  • Does the factory provide mechanical assembly or additional fasteners and adhesives?
    • Currently, such services are not available but can be considered based on customer demand.
  • Can the factory produce sub-assemblies or fully welded structures?
    • This depends on the specific product requirements.

  1. Surface Treatment and Post-Processing

  • Does the factory provide surface treatments like powder coating, anodizing, or polishing?
    • Surface treatments cannot be performed in-house due to environmental regulations.
  • Does the factory work with third-party surface treatment suppliers, and how are these processes managed?
    • Yes, third-party suppliers can be engaged. Standards are communicated, and production processes are tracked to ensure quality. Cooperation agreements specify quality standards and liability for non-compliance.
  • What quality checks are performed on finished products?
    • Quality checks are conducted based on customer specifications and domestic quality inspection standards.

  1. Quality Control

  • What quality assurance processes does the factory have?
    • ISO9001 quality certification.
  • Can inspection reports or certificates of conformity be provided with orders?
    • Yes, certificates of conformity and third-party inspection reports can be provided based on customer requirements. Additional costs will be negotiated if applicable.
  • How is dimensional accuracy and surface quality ensured?
    • Accuracy is ensured through drawings inspection, self-checks by production personnel, and follow-up inspections by quality inspectors. Materials are inspected upon arrival, and final products undergo factory inspection. Dedicated inspection tools are used, with records kept throughout the process.
  • What is the process for addressing quality issues or customer complaints?
    • In-factory quality issues are resolved promptly within each process. For customer complaints, the cause is identified, a solution is proposed, and resolution time is confirmed. The factory assumes responsibility for quality issues caused by its processes and collaborates to resolve issues outside its control.
