STJ1390 CO2 Laser Cutting Machine for 20mm Acrylic Sheet

STJ1390 laser acrylic cutting machine is equipped with square tube framework, with more than 40% higher fuselage strength than iron sheet structure. This design prevents the laser machine from quivering, resonance and distortion during long term work. New-style high-efficiency laser tube is adopted. Laser beam is more stable than the traditional type. Usage age is more than 10000 hours. Red dot position system is added in standard configuration, contributing to simple and precise working position. Humanized and modern appearance showing RECI's consistent humanity idea, making operation and maintenance quite easy. Advanced DSP control system with professional motion control chip has the function of consecutively high-speed curve cutting and the shortest path selection, which largely improves your acrylic cutting efficiency. 


Generic term for acrylic and methacrylic chemicals, including monomers, plates, pellets, resins and composite materials. Acrylic sheet is made by polymerization of methyl methacrylate monomer (MMA), namely polymethyl methacrylate (PMMA) sheet plexiglass, which is a kind of plexiglass processed by a special process. Has the reputation of "Plastic Queen".


Acrylic sheet has crystal-like transparency, and the light transmittance is more than 92%. Acrylic sheet colored with dyes has a good color development effect. In addition, acrylic sheet: has excellent weather resistance, high surface hardness and surface Gloss and good high temperature resistance. Acrylic sheets have good processing properties and can be divided into casting and extrusion types according to the production process. Both thermoforming (including compression molding, blow molding and vacuum suction molding) can be used, and mechanical processing methods such as drilling, turning, washing, and cutting can also be used. The mechanical cutting and engraving controlled by a microcomputer not only greatly improves the processing accuracy, but also produces more exquisite patterns and shapes than traditional methods. In addition, the acrylic sheet can be laser cut and laser engraved to produce products with peculiar effects.


Hardness is one of the parameters that best reflects the production process and technology of cast acrylic sheet, and it is an important part of quality control. The hardness can reflect the purity of the raw material MMA, the weather resistance of the sheet and the high temperature resistance. The hardness directly affects whether the plate will shrink and bend, and whether the surface will crack during processing. Hardness is one of the rigid indicators for judging the quality of acrylic sheets. The cast acrylic sheet has the highest hardness index at present, and the average Darlow hardness value is 90 degrees.


Acrylic sheet has excellent weather resistance, and is especially used outdoors. It ranks first among other plastics. It also has good surface hardness and gloss. It has great processing plasticity and can be made into various required shapes and products. The board has a wide variety of colors and rich colors (including translucent swatches), and another feature is that the thick board can still maintain high transparency.
