Q&A

ISO 9001:2015 certified and backed by 30 years of manufacturing experience, Sin-Ci Enterprise specializes in metal component processing and welding assembly services, including:

• TIG Welding (Argon Welding)
• MIG Welding
• Induction Brazing
• Laser Welding
• Spot Welding / Resistance Welding
• Robotic & Automated Welding
• Custom Fixture and Component Manufacturing
• OEM / ODM Component Manufacturing

We offer customized production tailored precisely to client drawings, production requirements, and quality standards.

Advantages: Welding joins two or more separate components by melting and fusing the metals together. It delivers superior joint strength compared to other fastening methods like bonding or mechanical fastening, making it an indispensable and ubiquitous process in industrial manufacturing.

Disadvantages: The intense heat of the welding process alters the crystalline structure of the metal within the heat-affected zone. Additionally, carbon-containing metals are prone to carbide precipitation, resulting in surface appearance changes that require secondary post-treatment.

Our primary processable materials currently include:

• Stainless Steel: SUS304, SUS308, SUS316, etc.
• Aluminum Alloys: 5052, 6061, 6063, 7075, etc.
• Ferrous Metals: Carbon Steel, Castings, Sheet Metal, etc.
• Special & Precious Alloys: Brass, Bronze, Silver, Gold, Titanium, etc.

For any special material requirements, please provide your technical drawings and specifications for further evaluation.

Yes, we do.

Hsin-Chi Enterprise fully supports our clients with:

• Sample & Prototype Development
• Engineering Verification Parts (EVT)
• Pilot Run / Trial Production Parts
• Low-Volume High-Mix Production

We assist our clients in completing thorough verification and design optimization prior to official mass production.

It depends on the product type.

• Prototyping Stage: Available from 1 unit.
• Low-Volume Production: 100 - 1,000 pcs (evaluated based on product complexity and structure).
• Mass Production Projects: 10,000 - 100,000+ pcs (can be scheduled based on annual forecast/requirements).

You are welcome to provide your technical drawings for our team's evaluation.

Standard Welding & Processing Components:

• Approx. 3–5 working days

Components Requiring Raw Materials & Multi-Stage Processing:

• Approx. 5–10 working days
• An additional 10 working days required if tooling/mold fabrication is involved

The actual delivery schedule will be finalized based on product structure and processing complexity.

The lead time depends on the following factors:

• Material procurement and lead time
• Number of processing and manufacturing stages
• Welding cycle time / man-hours
• Surface finishing requirements
• Order volume / quantity

Standard mass production lead time:

• Approximately 2–6 weeks

Urgent orders can be evaluated separately for expedited scheduling.

Please provide the following information:

• 2D Drawings (PDF)
• 3D CAD Files (STEP, IGES)
• Material Specifications
• Surface Finishing Requirements
• Strength / Mechanical Load Requirements
• Sealing Requirements (Airtightness / Watertightness)
• Estimated Order Quantity (EOQ) / Batch Size

Standard Quotation Turnaround Time:

• Welded Components: Approx. 3–5 working days
• Assembled Components: Approx. 5–10 working days
• Multi-part + Material Process Integration: Approx. 10–15 working days

Available upon request:

• Dimensional Inspection Reports
• First Article Inspection Reports (FAI)
• Material Certificates (Mill Certificates)
