Bending and Stamping Service

Wanluo supplier provide full-process OEM and ODM customized forming Bending and Stamping Service for rigging accessories, pipe fittings, hardware brackets, fastening parts and industrial sheet metal components. With custom mold development, one-time stamping forming and precise angle bending, we deliver standardized and personalized metal forming parts for global industrial customers, suitable for large-batch standardized customization and structural sheet metal hardware production.

Core Process & Production Equipment Advantages

We are equipped with high-speed stamping machines, hydraulic punching equipment, CNC bending machines, flattening machines and precision mold testing equipment, supporting full-process operations such as blanking, punching, hole cutting, embossing, edge folding, angle bending, shaping and leveling. Adopting professional die stamping technology, the metal sheet is formed in one step with no secondary cutting damage. The CNC bending system controls the bending angle and radian accurately, ensuring uniform bending force, smooth forming lines and no deformation or rebound. All molds are independently developed and calibrated, with high molding precision and long service life. Mass production realizes zero-size deviation in batches, greatly improving production efficiency while maintaining stable structural strength and appearance quality.

Customizable Processing Scope

1. Stamping Forming Parts: Custom stamped gaskets, flat washers, fixing plates, rigging connection sheets, pipe clamp brackets, locking pieces and various thin-plate stamping hardware. Support irregular punching, special hole position layout and pattern embossing customization.

2. Multi-Angle Bending Parts: Custom U-shaped, L-shaped, Z-shaped and multi-fold special bending structural parts, including equipment fixing brackets, reinforcing connecting plates and customized mounting supports for fasteners.

3. Integrated Forming Hardware: One-time stamping and bending integrated forming for handle clamps, spring pieces, elastic gaskets and special-shaped elastic fastening accessories, solving the assembly gap problem of multi-piece splicing parts.

4. Thickness & Structural Customization: Support customized metal sheet thickness, bending radian, opening size, hole spacing and overall outline dimensions to match customers’ actual assembly and load-bearing requirements.

Applicable Processing Materials

Suitable for various bendable and stampable metal materials: Carbon Steel Sheet, Galvanized Steel Sheet, Stainless Steel 201/304/316, Aluminum Sheet, Copper Sheet and Alloy Thin Plate. All raw materials have stable ductility and toughness, ensuring no cracking, no tearing and good forming effect during stamping and bending processes.

Surface Treatment & Finishing Technology

Provide complete post-forming surface treatment solutions: Electro Galvanizing, Hot-Dip Galvanizing, Zinc Plating Passivation, Black Oxide Treatment, Sandblasting, Polishing, Powder Coating and Anti-Fingerprint Treatment. Effectively enhance anti-rust, anti-corrosion and wear-resistant performance of stamped and bent parts, meeting outdoor engineering, marine humid environment and daily industrial use standards.

Core Service Advantages

1. High Efficiency & Low Cost: Bending and Stamping Service One-time mold forming supports large-batch rapid production. Compared with single-piece CNC processing, it greatly reduces unit cost and shortens delivery cycle, ideal for mass customized orders.

2. Excellent Batch Consistency: Standardized mold forming ensures identical size, angle and appearance of each product, with no batch difference, realizing high interchangeability of spare parts.

3. High Structural Stability: Cold forming process optimizes metal fiber structure, maintaining uniform material toughness. The bending parts feature strong anti-rebound performance and long-term structural stability without easy deformation.

4. Flexible Mold Customization: Support independent mold opening for customer exclusive structures. Custom private molds avoid universal standard part homogeneity, helping customers realize personalized product differentiation.

5. Complementary Process Matching: Perfectly cooperate with CNC machining, welding and assembly processes to provide integrated customized solutions from sheet metal forming, precision processing to finished product assembly.

Custom Process Flow

1. Customers provide drawings, samples or technical requirements 2. Technical team evaluates structure, recommends stamping/bending scheme 3. Custom mold development & trial production 4. Sample confirmation & dimensional verification 5. Mass stamping & bending production 6. Surface treatment, quality inspection & export packaging

FAQ

Q1: What is the difference between stamping/bending and CNC machining?

A1: Stamping and bending are suitable for large-batch thin-plate forming with low unit cost and high efficiency; CNC machining is suitable for high-precision complex special-shaped parts. We combine both processes to provide the most cost-effective solution according to customer product structure and order quantity.

Q2: Is custom mold opening required for stamping parts?

A2: For standard conventional parts, existing molds can be used directly with no mold fee. For exclusive special-shaped structures, we support customized mold development with flexible mold charge policies for large-batch orders.

Q3: Can you guarantee no rebound after bending?

A3: We adopt professional anti-rebound bending technology and precise angle compensation calibration. All finished parts are inspected by angle measuring instruments to ensure stable bending effect and meet assembly tolerance requirements.

Q4: What is the minimum order quantity for stamping customization?

A4: Small-batch trial production is acceptable. For new mold projects, a certain trial order quantity is required; for existing molds, we support flexible small-batch replenishment orders.

Q5: Can stamped and bent parts be processed with secondary precision machining?

A5: Yes. We support secondary CNC drilling, tapping, chamfering and finishing on stamped and bent blanks to achieve higher precision assembly standards and meet high-end equipment matching needs.
