Welcome to Cangzhou Honglang Hardware Manufacturing Co., Ltd. We are a professional manufacturer of custom metal deep drawing components and stainless steel stamped parts, dedicated to serving the automotive industry since 2018. With a factory spanning 3,000–5,000 square meters and a skilled team of 51–100 people, we combine advanced technology with rigorous quality control. Our deep drawing and stamping capabilities allow us to produce complex shapes with high precision, meeting the strictest requirements of automotive applications. Whether you need small brackets or large structural parts, our customized solutions ensure perfect fit and performance.
Our product range covers custom metal deep drawing components — from simple cylindrical cups to intricate multi-step drawn parts — all made from high-grade stainless steel to resist corrosion and withstand harsh conditions. We understand that automotive parts demand consistency and durability, which is why every piece undergoes strict dimensional checks and material verification. With certifications including ISO9001 and IATF16949, we guarantee a reliable supply chain for your production lines.
Key Features & Benefits
Customizable Dimensions: We offer any size from small precision parts (5mm diameter) to large panels (500mm), with thickness ranging from 0.3mm to 6.0mm. Tooling is designed based on your drawings.
Superior Material Choices: Stainless steel grades 304, 316, 430, and more are available. Each batch is certified for chemical composition and mechanical properties.
Complex Shapes Made Easy: Our deep drawing process can achieve draw ratios up to 2.5:1, enabling one-piece forming of shells, housings, and brackets with minimal seams.
High Precision & Consistency: CNC-controlled presses and automated feeding ensure tolerances as tight as ±0.05mm. Repeat orders maintain identical dimensions.
Versatile Surface Treatments: Options include polishing, passivation, electroplating, powder coating, or as-rolled finish. This enhances corrosion resistance and appearance.
Cost-Effective for Volume: Progressive die stamping reduces cycle time and material waste, making large quantities (10,000+ pieces) very competitive.
Industry Compliant: All parts are designed to meet automotive standards like SAE, ASTM, or customer-specific specifications. We also provide PPAP documents upon request.
