Description

Technical Field

[0002] Plastic board is a board made of plastic. Plastic is a synthetic polymer compound that can change its shape and style freely. Plastic is a material made by synthesizing or condensing monomer raw materials. It is composed of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants, colorants, etc. Its main component is synthetic resin. Existing board cutting technology generally only separates different materials by manual peeling or sawing, which has low processing efficiency and is easy to hurt hands. Roughly processed or molded plastic products have a certain hardness and cannot be further processed manually. They can only be trimmed using a plastic product cutting machine.
