Import Dj-7384 Flexible Board Copper-Plating Rack — Buy in Bulk from Supplier in China

The DJ-7384 flexible board copper-plating rack is constructed from SUS316L stainless steel, a grade known for its resistance to chloride-induced corrosion and stability in acidic plating baths. This material choice ensures prolonged service life under continuous electrochemical exposure, a critical factor in high-volume PCB manufacturing environments. The rack is designed with adjustable hooks and modular frame segments to accommodate varying board sizes and processing line configurations.

Standard industry tolerances for such racks are ±0.5mm in dimensional alignment and 0.1mm in hook spacing to prevent board warping during plating. The surface finish is electropolished to reduce adhesion of copper sludge and simplify cleaning cycles. While the listing confirms SUS316L material, it does not specify whether the rack includes insulating coatings on non-conductive contact points - a common feature in high-precision applications to avoid current leakage.

This rack is primarily used by electronics manufacturers producing rigid-flex PCBs, automotive control modules, and aerospace circuitry where uniform copper deposition is essential. Buyers in these sectors typically order in batches of 10 to 50 units depending on production line scale. Trade terms are not listed, but standard arrangements include FOB Guangzhou or CIF destination port. Packaging is typically wooden crates with foam inserts to prevent deformation during transit.

The rack is compatible with continuous horizontal plating lines and vertical batch systems. Its flexibility allows for reconfiguration without tooling changes, reducing downtime between product runs. Buyers should confirm compatibility with their existing rectifier and pump system flow rates, as improper flow dynamics can cause uneven plating thickness.

Hongdinng Dianjing Technology Co., Ltd. is based in Nance Village, Dongfeng Industry, Hum To Dongguan, Guangdong, China. The listing identifies the supplier as imported and harbor-trusted, indicating verified export compliance and logistics readiness. No company history, employee count, or client list is provided. The supplier’s profile does not claim certifications, awards, or years in operation.

The supplier specializes in custom plating fixtures and racks for industrial electroplating systems, with a focus on the electronics manufacturing sector. The listing shows no evidence of in-house R&D, testing labs, or ISO documentation. Response rate and average response time are zero, suggesting no active sales or inquiry handling. Buyers should treat this as a factory-level producer without direct customer service infrastructure.
