Material description Raw

PC resin has an unparalleled impact resistance, excellent dimensional stability and crystal like transparency, has been a leader in polycarbonate. It is an amorphous engineering thermoplastic material with excellent mechanical, optical, electrical and thermal properties. Lexan resin for designers to provide new opportunities, used to produce innovative, economical and practical products such as goggles, CD, kitchen utensils and commericial.

PC resin has a special effect series, for example: Intrigue (Magic) diamond (diamond). The special appearance and color can make your product unique. With many different additives, such as UV stabilizer and release agent, Lexan resin can be extended to meet the FDA standards, high mobility and glass fiber reinforced grade.

PC resin with high impact strength, internal crystal like transparency, the product purity, viscosity and durability of 125 resistance temperature -RTI up, dimensional stability under high temperature environment, rich colors, transparent, thou and opaque both resistance flammability and UV stability, meet FDA standards, excellent processing performance

Application range Typical

Shell and computer peripheral equipment, houses and buildings - glass windows, optical lens, correction with goggles, sunglasses, CDs, DVDs, health care products, Aquarius, mobile phone shell, shell of electronic equipment, little guidance

Injection (PC) process Polycarbonate

PC known as polycarbonate, due to its excellent mechanical properties, commonly known as plastic plates. PC has the characteristics of high mechanical strength wide use, temperature range, good electrical insulation performance (but the arc resistance is constant), size stability, transparency and, so on. Widely used in electrical products, electronic products, instrument shell structures. PC modified products more often have to add glass fiber, mineral filler, chemical flame retardant, other plastics, etc.. PC has poor mobility and high processing temperature, so it is necessary for the processing of many levels of modified materials to be specialized in plastic injection structure.
1, processing plastic
The water absorption rate of PC is high, and it must be pre processed before processing, pure PC is dry 120, and the modified PC is generally used for drying at 110 for 4 hours. Drying with MgSO4 and concentration time can not exceed 10 hours. It is generally available to determine whether the air extrusion method is adequate.

The use of recycled material can reach 20%. In some cases, 100% of the use of recycled material, the actual amount of the quality of the product to be. Recycled materials cannot be mixed with different color at the same time, otherwise it will seriously damage the product.

2, molding machine selection injection
Now the PC products due to cost and other aspects of the reasons, modified materials, especially electrical products, must increase the fire performance, flame retardant PC and plastic alloy products molding, the requirements to the plastics injection molding machine system is mixed, resistance to corrosion, CUF plasticizing screw is difficult to achieve, at the time of purchase, be sure to be described. The Ramada company has PC special screw for customer selection

3, and gate design mould
The common mold temperature is 80, and the glass fiber is 130, and the small products can be used for needle shaped gate, the depth of the gate should be 70% of the most thick. The other gate is circular and rectangular.

Bigger the gate the, better to, reduce the plastic to be excessive shear caused by defects. The
Depth of the vent hole should be less than 0.03-0.06mm and, the flow channel is short and round. The
Draft is usually'About 30 -1°. The

4, temperature melt
Can be used to determine the processing temperature of air injection. The processing temperature of PC was 270-320, and some modification or low molecular weight PC was 230-270.

5, speed injection
The use of partial fast injection molding such, as electrical switches. Common for slow Fast - forming. - See

6, pressure back
Around the back pressure in, the absence of gas lines and mixed color can be appropriate to reduce. 10bar

7, time retention
At high temperature for too long the, material will be reduced quality Stay, CO2 put, yellow. Do not use LDPE POM, ABS, or PA tube cleaning machine. PS cleaning. become
