Import Deep-Draw Parts Manufacture-Battery Contact — Buy in Bulk from Supplier in China

Deep-draw battery contacts from Shenzhen Kunzhan Plastic Hardware Co., Ltd. are precision-formed components designed for reliable electrical connection in compact battery assemblies. The contacts are manufactured using deep-drawing techniques to achieve consistent wall thickness and dimensional accuracy, with materials specified as high-grade metal alloys suitable for low-resistance current transfer. These parts are not plated or coated in the source data, but standard industry practice for such contacts includes nickel or silver plating to enhance conductivity and resist oxidation in humid environments.

The base material is typically a copper alloy or beryllium copper, chosen for its balance of electrical conductivity, spring characteristics, and formability. The deep-draw process allows for complex geometries with minimal material waste, critical for high-volume production. While the listing does not specify tolerance ranges, standard industrial tolerances for such contacts are ±0.05 mm for critical contact surfaces and ±0.1 mm for outer dimensions. Surface finish is typically uncoated unless otherwise requested, with no mention of RoHS or REACH compliance in the source.

These contacts are used in button cell batteries, coin cell holders, and small lithium-ion packs for wearables, medical devices, and IoT sensors. Buyers include OEMs in consumer electronics and contract manufacturers sourcing low-cost, high-volume components. Trade terms are not specified in the source, but bulk orders typically require minimum quantities of 5,000 units or more. Packaging is usually in bulk trays or anti-static tubes, with lead time estimated at 15 to 25 days after order confirmation. Buyers should confirm material certification and plating requirements directly with the supplier.

Shenzhen Kunzhan Plastic Hardware Co., Ltd. is based in Angxiayong Village, Songgang Town, Shenzhen, Guangdong. The company is listed as an imported supplier with harbor-level trust verification, indicating confirmed business registration and physical address. There is no public information on company history, workforce size, or annual output volume. The listing does not claim certifications, awards, or client names. The supplier's focus appears limited to metal stamping and deep-draw components for electronics, with no indication of in-house R&D or tooling design capabilities.

Response rate and average response time are recorded as zero, suggesting limited or inactive communication channels on the platform. Buyers should not assume real-time support or automated quoting. The supplier’s operational capacity is inferred only from the product listing and address verification. No export experience, past shipments, or third-party audit reports are referenced. Sourcing decisions must be based on sample evaluation and direct confirmation of specifications, not platform claims.
