Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer specializing in custom springs and wire products. With an annual export value of US$5 million to US$10 million, we serve a wide range of global markets including North America, Europe, Asia, and Oceania. Our Custom Special-Shaped Spring is designed to meet the most demanding mechanical requirements, offering unique geometries that standard springs cannot provide. Each spring comes with a 1-year warranty and free technical support, along with a full material report to ensure quality and traceability.
Our special-shaped springs are engineered for applications where precise force, deflection, and space constraints are critical. Whether you need a spring with a complex geometry, non-standard wire diameter, or specific surface treatment, we can manufacture it to your exact specifications. The springs are produced using advanced CNC coiling machines and undergo rigorous quality control checks to ensure consistent performance.

Our special-shaped springs are used in a variety of industries: automotive (clutch, brake, suspension), electronics (connectors, switches), industrial machinery (valves, actuators), and medical devices (surgical tools, implants). The unique shape can be designed to fit into tight spaces, provide specific load curves, or accommodate multiple functions in one component.
Compared to off-the-shelf springs, custom special-shaped springs offer several benefits: reduced assembly time, improved performance, lower overall system cost, and enhanced product reliability. Our engineers work closely with clients to optimize the spring design for manufacturability and cost efficiency.

Frequently Asked Questions
Q1: What materials are available for custom special-shaped springs?
A: We offer a wide range of materials including high-carbon steel (SAE1070), stainless steel (304, 316), alloy steel (17-7PH, 60Si2Mn), and copper alloys. Please specify your requirements, and we will recommend the best material for your application.
Q2: How do I submit a custom spring design?
A: You can send us a 2D drawing (PDF/DWG), 3D model (STEP/IGES), or a simple sketch with dimensions and load requirements. Our engineering team will review and provide feedback.
Q3: What is the typical lead time for custom springs?
A: Lead time varies by complexity and quantity. Standard prototypes take 7-10 working days, and mass production typically 15-25 working days. We offer expedited services for urgent orders.
Q4: Do you provide samples before mass production?
A: Yes, we can produce samples for your approval. Sample costs are negotiable, and we will deduct the sample cost from the mass production order.
Q5: What is included in the material report?
A: The material report includes chemical composition analysis, tensile strength, yield strength, and hardness test results. It is issued by an accredited testing facility.
Q6: How do you ensure the spring's performance matches the design?
A: We use load testing machines to measure force at specific deflections, and dimensional inspection to verify all critical parameters. A test report is available upon request.
Q7: What is the warranty coverage?
A: The 1-year warranty covers manufacturing defects such as improper material, incorrect dimensions, or premature failure under normal use. It does not cover damage due to misuse or improper installation.
Q8: Can you produce springs with very tight tolerances?
A: Yes, we can achieve tolerances as tight as ±0.01 mm for critical dimensions, depending on the spring geometry and material. Our QC team uses precision measuring instruments to ensure compliance.
