Electronic Accelerator Pedal Spring Solutions

CATALOG Springs has been an active participant in the automotive industry since 2016, establishing this sector as one of our three core business pillars. Our customer portfolio includes leading domestic and international manufacturers in solenoid valves, booster valves, steering systems, and electronic accelerator pedals. We serve as a designated supplier for multiple global and domestic OEMs, including GAC, SAIC, Geely, Wuling, and Great Wall.

Our management and core technical team bring over ten years of experience from multinational spring enterprises, supported by extensive expertise in project development and production management.

With the advancement of automotive electronics, electronic accelerator pedals—both floor‑mounted and suspended designs—have largely replaced traditional cable‑type mechanisms. The return spring, as a critical component, directly influences pedal responsiveness, return accuracy, and overall driving feel. CATALOG delivers high‑quality, integrated solutions encompassing design, material selection, and rigorous validation, helping customers enhance product reliability and performance.

Electronic Accelerator Pedal Spring Solutions: Challenge & Response

Challenge	CATALOG's Response	Outcome
Unstable spring force (too high/low) Affects pedal feel and driver experience due to traditional design and process variations.	Simulate stiffness, force, stress, and resonance risks using the Huaxia Xing Intelligent Platform. Implement strict full-process control and process discipline.	Accurate, consistent force output that matches the driver's tactile expectations.
Fatigue failure & insufficient corrosion resistance Must withstand long-term low-frequency cycling while resisting rust in varied environments.	Select high-grade piano wire or oil-tempered wire; validate with 10-million-cycle bench fatigue + 100,000-km road tests. Apply professional post-treatment; pass 96-hour salt-spray testing.	Fatigue-resistant, corrosion-proof springs that meet or exceed German and Korean end-customer road-test standards.
Special material requirements & long lead times High-end pedal designs demand specific imported materials that standard suppliers often lack.	Maintain 700+ material grades in stock, with over 90% being imported piano wire, Baosteel stainless steel, etc. Direct sourcing from European/American specialty-material suppliers ensures genuine imported stock.	Rapid material response, shorter lead times, and customized post-processing support.

Enhanced Fatigue Life & Reliability

We select piano wire or oil‑tempered wire engineered for long‑term low‑frequency cycling. During development, each design must pass 10‑million‑cycle bench fatigue testing, 100,000‑km vehicle road validation (exceeding conventional 3‑million‑cycle standards), and 96‑hour salt‑spray corrosion testing, ensuring rust resistance and performance comparable to imported quality—and validated through end‑customer road tests in Germany and South Korea.

Precision Force Control & Consistency

Using our in‑house Huaxia Xing Intelligent Platform and professional simulation tools, we rigorously calculate spring rate and force values, simulate stress distribution and resonance risks across operating ranges, and validate design effectiveness. Strict process controls throughout production guarantee accurate, stable force output and optimized pedal tactile response.

Premium Materials & Supply Stability

We source both imported and domestic high‑grade materials, maintaining an inventory of 700+ material grades—over 90% of which are wire imported from South Korea, along with Baosteel stainless steel, high‑temperature alloys, and other specialty stocks. Through direct partnerships with U.S. and European specialty‑material suppliers, we ensure genuine imported quality and offer tailored post‑processing to meet specific application requirements.
