PCM / VCM

Introduction

PCM is used special steel coil as raw material and surfaces is painted a layer of orgainic ploymer or polymer print film, which has advantaged of metal adn organic polymer, not only good adhesive of organic polymer, formability, corrosion resistance, decorative, but also high strength and easy processing, can be easily puching, bending, deep drawing, welding. etc. So it has perfect practicality, decorative, workability, durability. Currently, the PCM is produced by print film roller coating process and roller painting.

Raw Material

Steel coil

PCM have cold-rolled sheet, galvanized steel and Aluzinc

PCM thickness: 0.3-0.8mm, cold rolled meterial typically is used for SPCC (general usage), SPCD (punch), SPCE (deep punch), and other products, chemical composition and physical properties as follow


Coating

Due to higher require of PCM surface, PCM with topcoat paint is generally used in high quality polyester painting, which need to be clean ,free of impurtities and grain material trees, usually on the line needs to be filtered. In order to improve the durability of home appliance, especially for door use appliance, can use high-performance silicon-modified polyester coating, fluorocarbon coating.

PVC/PET Film

VCM is used in PVC or PET film as a general base film, and then printed different decorative patterns on the surface, so that the VCM can be use widely on refrigerator door panels

Protective film

During the molding process for forming the line, in order to avoid scratch on surface in processby several times, PCM and VCM have to be covered with layer protective film on surface.

Production line

Application



According to the different production process, pre-painting steel coil can be divided into PCM and VCM with printed film. PCM is used for refrigerators, washing machines, freezers and other applicances door,electric appliances lateral plate, microwave oven,video disc, TV backplate; VCM is mainly used for refrigerator doors, washing machines and other appliances

According to different appliances usage, PCM can be divided into white home appliance and black home appliance.
