Plastic Granules Making Machine Processing Contracting Problem Oct 13, 2017

The problem of plastic shrinkage is one of the most common problems in the processing of plastic granules making machine.
Shrink is a tricky problem!
Therefore, with the plastic granules making machine from time to time to improve the processing of plastic granules making machine to solve the problem of shrinkage, improve the quality of products is imperative plastic granules making machine processing shrinkage marks the presence of plastic shrinkage. Cooling runner design, gate type, gate size may occur a variety of effects. For example, a small gate, such as a pipe gate, is much faster to cool than a tapered gate. Premature cooling at the gate reduces the filling time in the cavity, increasing the chances of contraction marks.
For the molding workers, adjusting the processing conditions is a way to solve the problem of shrinkage of plastic granules making machine. Filling pressure and time significantly affect shrinkage. After the parts are filled, the excess information continues to fill the cavity to compensate for the shrinkage of the material. Filling phase is too short will lead to increased contraction, and ultimately will occur more or larger shrinkage marks. The shrinkage method itself may not be able to reduce the contraction marks to a satisfactory level, but the molding workers can adjust the filling conditions to improve the shrinkage marks.
But also in the actual development process, the recycled plastics face many problems, such as the quality of the source of Qi Qi Qi, the quality of poor stability, but also in the development of energy, Recycling enterprises to small and medium-sized, the industry is too scattered, the cost is higher than the original plastic, etc., have become the issue of recycled plastic on the road. Recycled plastic processing equipment manufacturers uneven, but also caused the development of recycled plastics a major obstacle.
1, renewable plastic granules making machine full use of high pressure friction uninterrupted heating system, automatic heating production, to avoid continuous heating, energy saving.
2, plastic granules making machine using split automatic power distribution system to ensure the normal operation of the motor safety.
3, plastic granules making machine appearance of the international fashion color, beautiful and generous.
4, all recycled materials by classification and broken after cleaning without drying or drying, drying, you can produce, wet and dry, processing bags (such as: rice bags, cement bags) can not be disconnected, not cut edge, direct Broken clean.
5, peeling water-cooled regeneration granulation machine is the plastic in the melt state was cut by the blade, the cooling water after the circulation of solidification, different viscosity of the polymer can be used in this form of pelletizing, Will produce any dust, to avoid the traditional dredging caused by dust pollution and waste.
Recycled plastic granules making machine is the use of waste plastics recycling process re-use, then the different plastic materials in the process of what will happen after the change? Waste plastic contains our waste plastic products, plastic semi-finished products or plastic raw materials, so these plastics will cover the different materials of plastic, plastic materials like PVC in the recycling process after the color will be different with the number of processing And after a regeneration of extrusion will be with a light brown, three times almost become opaque brown;
PE plastic granules making machine with the same PVC plastic, color processing after the yellowing after processing, with the increase in the number of processing of its high-density polyethylene viscosity decreased, while improving the viscosity of low-density polyethylene; PP material after the plastic recycling The color change is not large, but the melt index increases, breaking strength and elongation has declined but does not affect the use of PS material after the plastic processing of color yellowing, plastic granules making machine the performance of the degree of decline is proportional to the number of regeneration; ABS material After the plastic processing of plastic color change significantly, the nature of little change.
