  How to Select Coatings for Metal and Plastic Coating? Key Points for Material and Paint Selection

  2026-09-24

  Metal and plastic workpieces feature vastly different material properties, and their paint coatings cannot be used interchangeably. Improper coating selection may trigger defects including poor adhesion, paint peeling, cracking, yellowing and insufficient corrosion resistance. When conducting metal‑plastic coating processing, enterprises shall make scientific selections according to substrate material, service environment, functional requirements and appearance standards. Balancing paint‑film adhesion, durability and visual quality helps cut rework costs and improve finished‑product qualification rates.

  What Is the Difference Between Metal Coating and Plastic Coating?

  2026-09-24

  Metal coating and plastic coating are two mainstream surface‑treatment processes widely used for hardware components, home‑appliance housings, mechanical equipment and plastic products. Though both serve for coloring, protection and corrosion resistance, they show notable differences in adhesion mechanism, pre‑treatment procedures, paint selection, curing temperature and finished‑part performance due to distinct substrate properties. Processes cannot be interchanged; otherwise paint peeling, cracking and poor adhesion are likely to occur.

  How to Solve Corrosion and Wear Problems Through Metal Surface Treatment

  2026-08-25

  During long-term service, metal materials are prone to surface rust, peeling, abrasion and scratches due to air oxidation, acid-base medium erosion, mechanical friction and humid outdoor environments. These defects not only damage the appearance and precision of workpieces and reduce the operational stability of equipment, but also greatly shorten service life and increase corporate maintenance and replacement costs. Professional metal surface treatment processes can block corrosive media from the source and strengthen surface hardness, effectively solving the two major industrial problems of metal corrosion and wear, and serving as a core method for long-term protection of industrial equipment.

  Classification, Principles and Industrial Application Summary of Metal Surface Treatment Processes

  Metal surface treatment is a basic supporting process for industrial precision manufacturing. It modifies the surface layer of metal workpieces through physical, chemical or mechanical means to effectively eliminate surface defects, optimize material properties and enhance appearance texture. This process solves common industrial pain points of metals such as easy corrosion, oxidation, rough surface and poor wear resistance, greatly extending the service life of workpieces and increasing product added value. It is widely applied in numerous industrial fields including hardware, machinery, molds, auto parts and precision equipment.
