About Shanyo Precision
Qingdao Shanyo Precision Electronics Co., Ltd. is a leading China manufacturer of precision metal domes and tactile switch components with over 20 years of stamping expertise. Serving global welding equipment OEMs, we combine advanced SUS301 stainless steel technology with IATF 16949 certified quality systems.
Our 8,000㎡ factory houses 12 high-speed precision stamping lines, delivering 50 million+ domes monthly to customers in 40+ countries.
Welding Metal Dome: Product Overview
Shanyo welding metal domes are precision-stamped from SUS301 spring stainless steel, specifically engineered for the demanding control interfaces of welding equipment. These tactile snap domes provide crisp, reliable button feedback in MIG/TIG welders, plasma cutters, spot welders and robotic welding teach pendants.
Unlike standard consumer-grade domes, our welding-grade series features enhanced high-temperature resistance up to 125°C, reinforced contact geometry for industrial vibration environments, and optional gold or silver plating for corrosion resistance in harsh welding workshop conditions.
Available as loose individual domes or pre-assembled PET film arrays with 3M adhesive, our welding metal domes support both through-hole and surface-mount PCB designs with full custom tooling capabilities.

Frequently Asked Questions
Q: What is the minimum order quantity for welding metal domes?
A: Standard MOQ is 10,000 pieces for loose domes and 5,000 pieces for PET film arrays. Custom tooling orders start at 50,000 pieces with tooling fee waived at 200K+ annual volume.
Q: Can you provide free samples for evaluation?
A: Yes, we offer free standard samples (up to 50 pieces) within 3-5 working days. Custom force or shape samples require 7-10 days with a small tooling deposit refundable on bulk order.
Q: What plating options are available for welding environment?
A: Standard SUS301 stainless steel with optional gold (Au), silver (Ag) or nickel (Ni) plating. Gold plating recommended for high-humidity welding workshops; silver for high-current contact applications.
Q: What is the typical lead time for bulk orders?
A: Standard in-stock sizes ship within 7-10 days. Custom force or array layouts require 15-20 days including tooling. Expedited service available for urgent OEM production needs.
Q: Do your welding metal domes meet automotive standards?
A: Yes, our facility is IATF 16949 certified. All welding-grade domes undergo PPAP documentation, vibration testing (10-500Hz, 5G), thermal shock (-40°C to +125°C) and 1M+ cycle life validation.
