Metal Bar - Precision Decorative Bar for Mobile Phone Protection Case

Product Overview

This Metal Bar is a specialized precision decorative component exclusively developed for mobile phone protection cases, serving as a high-grade external decorative strip embedded and fixed on the surface of mobile phone cases to enhance product texture and appearance grade. As a directly visible appearance accessory for mobile phone protective gear, this product has strict requirements for surface smoothness, dimensional accuracy and scratch resistance, and adopts a pure OEM customized production model, with all manufacturing processes implemented in strict accordance with customer-provided engineering drawings and process requirements.

We select 0.8mm thick H62 brass as the special raw material for this metal bar, a material with good ductility, formability and excellent electroplating adhesion, perfectly matching the appearance and post-treatment needs of mobile phone case accessories. Our technical team has designed a customized high-precision progressive die with a built-in pneumatic cutting unit, tailored to the customer's subsequent electroplating process requirements; during mass production, the material strip will be automatically pneumatically cut into groups of 20 pieces after stamping forming, and the grouped semi-finished products can be directly transferred to rack electroplating, greatly optimizing the post-treatment process and improving production efficiency. The product is equipped with 0.4mm steps on the upper and lower sides, which are formed by in-die extrusion stamping to ensure step consistency and dimensional accuracy. We adopt professional anti-collision packaging for finished product delivery to avoid surface scratches during transportation and storage, with a stable monthly delivery capacity of 500,000 pieces to meet the large-scale supporting needs of mobile phone case manufacturers.

Core Product Functions

This Metal Bar undertakes multiple core functions tailored for mobile phone protection cases, focusing on appearance upgrading, structural matching and process adaptability, which directly affects the overall texture and market competitiveness of mobile phone cases. Primarily, it acts as a high-end decorative component on the surface of mobile phone protection cases, breaking the monotony of pure plastic or ordinary case materials, and enhancing the exquisite and high-end appearance of mobile phone cases with the metallic texture of H62 brass, meeting the aesthetic needs of consumers for personalized and high-quality mobile phone accessories. Secondly, the 0.4mm steps on the upper and lower sides are designed for precise embedded assembly with the mobile phone case body, achieving tight and firm fitting without gaps or looseness, ensuring stable installation during daily use and handling of the mobile phone case.

In addition, the product's structural design is highly compatible with the subsequent rack electroplating process, and the grouped pneumatic cutting mode avoids the trouble of manual sorting and loading during electroplating, improving the efficiency and uniformity of electroplating treatment. The smooth and burr-free surface formed by precision stamping ensures a uniform and glossy effect after electroplating, further enhancing the appearance quality of the finished mobile phone case. As an external decorative part, it also provides a certain degree of edge protection for the mobile phone case, reducing wear and tear on the case surface during daily placement and friction.

Key Product & Production Features

This mobile phone case Metal Bar has exclusive technical and process advantages tailored to the digital accessory industry, with electroplating-friendly process design, precision in-die forming and anti-scratch protection as core highlights, completely differentiated from previous beauty, electrical and mechanical stamping parts. The selection of 0.8mm H62 brass is a precise choice for decorative electroplating parts, with better formability than ordinary steel and more stable electroplating adhesion than conventional copper materials, ensuring no blistering or peeling after electroplating. The biggest process highlight is the customized progressive die with pneumatic cutting function, which can automatically cut 20 pieces in a group during continuous stamping, perfectly matching the rack electroplating process and eliminating manual cutting and sorting links.

The 0.4mm upper and lower steps are formed by in-die extrusion stamping, with high dimensional consistency, smooth transition and no burrs or cracks, ensuring seamless assembly with mobile phone cases. The entire stamping process is controlled with high precision to ensure the flatness and smoothness of the product surface, laying a good foundation for subsequent electroplating. We adopt special anti-collision packaging for finished products, with built-in buffer isolation between each product to avoid friction and extrusion scratches during transportation and storage, fully meeting the high appearance requirements of mobile phone digital accessories. No additional pre-treatment is required before electroplating, and the grouped semi-finished products can be directly put into electroplating, saving production time and cost for customers.

Product Specifications & Production Capacity

This Metal Bar adopts a full OEM customized model, with no fixed unified standard specifications, and the length, width, 0.4mm step size and overall shape are all formulated according to customer-provided drawings or samples. The fixed raw material is 0.8mm thick H62 brass, the core production process is high-precision progressive stamping with in-die extrusion forming and pneumatic automatic cutting, and the standard post-treatment process is professional rack electroplating. By default, no special performance testing is arranged, and targeted surface flatness and dimensional tolerance testing can be added according to customer special mobile phone case requirements. The conventional packaging method is professional anti-collision packaging, with independent buffer protection for each product to ensure the surface is free of scratches during transportation and storage.
