Hongzhe hardware stamping parts teach you how to judge the quality of hardware products?

From the past history into the modern industrial era, the precision hardware industry in Dongguan is developing rapidly. Hongzhe hardware products can be seen everywhere in every family. Although hardware products are installed in the home only as an accessory, we must also choose carefully. Small losses, such as rust, peeling, and looseness, all bring unpleasantness to our lives. Below, Hongzhe Hardware Products will first share the ways to distinguish between good and bad hardware:

1. How to identify raw materials for Hongzhe precision hardware products

Inferior products: use defective zinc alloy recycled materials and cut corners to reduce costs. For example, many defective products use recycled aluminum, which has a loose structure, light weight and a light feel.

Excellent products: Choose sand-finished copper, high-quality zinc alloy or titanium alloy, with tight structure, heavier weight, and solid hand feeling. The raw material is pure copper. The copper tube wall thickness is generally 0.6-0.8m. For example, Kohler’s bathhouse racks are very well done even in details, with smooth feel and stable structure.

2. How to distinguish the quality of accessories for Hongzhe hardware products

Inferior products: fasteners are made of iron screws, which are easy to rust.

Excellent products: The fasteners are stainless steel screws or copper screws, and the glass products are imported glass rings and plates, which are uniform in thickness, high in transparency and clear in vision.

Three, identify hardwarePrecision castingAnd processing quality

Inferior products: use small die-casting machines and rough machine tools, lack of pressure, products with pores, silk patterns, cracks, and inequalities on the surface of the product, rough polishing process, rough working procedures.

Excellent products: Large-scale fine computer-controlled die-casting machine tools and digital fine machine tools are used. The surface of the blank is lubricated, smooth, free of pores, and silk defects. The grinding and polishing process is rigorous and the process is complicated.

Fourth, identify the coating

Inferior products: low-cost brighteners are used for electroplating, with loose structure, poor bonding, dull and whitish gloss, because direct chromium plating on zinc alloys is very easy to rust, wear, blisters, and fall off in a short time. The thickness of the coating layer is short of 3 microns, and there are many scratches and burrs on the surface of the coating layer.

Excellent products: bright electroplating layer, good bonding force, tight structure, uniform coating, crisp color, and the thickness of the coating is generally above 6 microns.

Five, identify the packaging

Inferior products: The packaging box uses poor raw materials, rough printing, and fuzzy trademarks. Generally, the manufacturer is not indicated on the packaging and the inner box, or even "three-no" products.

Excellent products: The packaging plan is beautiful, the trademark is clear and eye-catching, the manufacturer and the detailed address are generally indicated, and the inner box has a quality inspection certificate and a description of the device.

Sixth, hardware after-sales service

Inferior products: There is no after-sales service at all, and there is no effective device specification or quality assurance certificate for internal integration.
