1. Advantage of plastic mold processing
Generally speaking, Plastic uptake processing can be used for processing large size thin-walled products, and allow the product with undercut. The main advantages of plastic uptake processing is that equipment and tooling cost is low,it’s an economical processing method.
However because of the plastic sheet plastic properties Limited, and the working pressure is too small (Only one atmosphere) or other reasons. Vacuum processing is not suitable for plastic products which have complex processing structure(such as Non thick products, with insert products ) and the products with thick wall.In addition,Plastic processing also has more shortcomings such as nonuniform wall thickness,unstable size,too much subsequent processing.
Besides,Plastic uptake is mainly used for packing and some hin-walled parts with low accuracy.Due to the mold is very simple, parts material is PE and PVC ,etc. So the machining cost is low, but its shortcomings are physical performance parts strength and electrical performance is poor, low precision, also can not machining complex parts.

3. ABS Acrylonitrile process conditions
Drying process: ABS is Hygroscopic, Drying is required prior to processing.
Suggested drying conditions for at least 2 hours under 80~90 ℃ drying. Material temperature should be less than 0.1%
fusion temperature: 260~290℃ .Suggested temperature: 275~280℃.
Die temperature: 25~70℃ (Mold temperature affects plastic finish, low temperature will lead to low finish)
Injection pressure: 500~1000 bar.
Injection speed : slower than high speed .
So grasp the plastic packaging bag processing technology is very necessary
4. PA66 polyamide 66 process conditions
Drying process: If the process of material is sealed, it is not necessary to dry.But if Jelly plastic packaging containers are open, then it’s recommended using hot air drying at 85 ℃ . When the humidity is greater than 0.2%, vacuum drying at 105 ℃ for 12 hours
fusion temperature: 260~290℃ .For glass added : 275~280℃. The melting temperature higher than 300 ℃ should avoid.
die temperature: 80℃. die temperature significantly influences the degree of crystallization and the crystallinity affects the mechanical properties. For thin plastics, if using the die temperature below 40℃,Crystal plastic degree changes with time. In order to keep the geometric stability of plastic parts, the need for annealing is needed.
injection pressure : generall 750~1250bar. Depends on the material and product design
injection speed : High speed (for enhanced materials should be slightly lower.
5. PA12 polyamide 12 process conditions
Drying process:Due to the water absorbility of PA6,special attention should be paid to the process before the drying. If the plastic processing plant material is packed in waterproof material supply,then the containers should be kept closed. When the humidity is greater than 0.2%,it is suggested that take hot air drying at above 80 ℃ in 16 hours.But if the material has been exposed in the air over than 8 hours, it’s better to take vacuum drying at 105 ℃ for 8 hours.
fusion temperature: 230~280℃ .For Enhanced varieties: 250~280℃
die temperature: 80~90℃. die temperature significantly influences the degree of crystallization and the crystallinity affects the mechanical properties
Crystallinity is very important for structural unit,therefore the temperature 80~90℃ is suggested.For thin, long-flow plastic is also recommended using high mold temperature. Increasing the mold temperature would increase the strength and stiffness, but the toughness is decreased.
6. Plastic product market
Q: How is marketing of plastic products.
A: With the development of the gasline industry, plasticc has been permeate into details of daily life flowing like water.Or it can be said playing a decisive role in people’s life.By the unique lightness ,high plasticity,excellent chemical properties and cheap price ,it has already replaced many kinds of material and been the the most widely used, the highest use rate of raw material
At the same time ,more and more other material has been kicked out from marketing by plastic industry. Many products have been taking plastic production instead of others,therefore the potential has been stimulated. For a short time, plastic packaging, plastic parts, plastic furniture, plastic cutlery, plastic books, plastic doors and windows, plastic toys, plastics, clothing and many other plastic products debut,many well-selling products are being created one after another
Because of various kinds of plastic raw materials and different characteristics ,plastic has different uses for specific purposes.Nowadays plastic has been used into provisions,hospitality,electronics, electrical instrumentation,machinery,chemistry.
cosmetics,medicine,apparel,toys,stationary ,transportation industries and so on.It can be said that the potential of plastic products market is very huge,and there are tens of thousands of products are able to be plasticized and also don’t neglect the new products to be developed.
7. Multilayer blow molded plastic processing
Multilayer blow molding is one of the hollow blow molding technologies.It functions by using blow molding method with multilayer composite preforms to make laminated layer vessel.
The main purposes of the development of multi-layer blow molding technology are to overcome some of the inherent shortcomings of the single layer plastic containers by each layer of the plastic properties of the effective complementary through varied reasonable matchings of the plastic layers.
Single-layer plastic container could not be or more difficult than high performance products,meanwhile it more often than not saves the cost through saving the application amount of expensive plastic layer under the premise of that the performance of containers’ using is ensured
Multilayer blow molding also can be classified in accordance with the implementation of multi-layer blow molding methods. On the basis of methods of making preforms, multi-layer blow molding can be divided into co extruded multilayer blow molding and coinjected multilayer blow molding.
Coinjected multilayer blow molding is a method that making performs by using co-extrusion method. Plastics processing plants divide it into continuous extrusion and material storage cylinder co extruded multilayer blow in accordance with different kinds of extrusions.
Multilayer blow can be divided into multilayer stretch blow molding and multi-layer non stretch blow molding. In addition to Multilayer stretch blow molding,other multi-layer non stretch blow moldings are generally called multi-layer blow.
8.What kinds of plastic products can be made by LDPE
Low density polyethylene(LDPE) resin can be made into Plastic Products by the methods of extrusion, injection, blow molding and die casting methods etc.
By using extruders,it can be made into formed films,tubings,sheets,varied special-shaped products and wire insulation protective layer products,etc.And by using blow molding methods,it can be made into hollow containers like formed blown films,extrusion blow molded bottlesand barrel and so on.
By using injection machine,it can be made into formed life communities,stationaries,toys and some industrial fittings ,etc.
9. What is the plastic products
Plastic product is a kind of product made by using die casting ,filling etc, to press the resin(plastic) as raw materials .
The number of Chinese plastic factoriues and the quantity of plastic production are in the front rank amongthe world.Many plastic products have been the “World Bests”and keep growing with a 15% increase.
There are many and varied features of plastic products.First,the lightness and low desity.Compare with the denser iron(8.3),plastic(0.9-2.2) is much more convenient for its usages.
nsulation is also one of the great features.The most important reason why plastic products are widely used in mechanical field and industrial field is due to the abilities of being more secure and less consumption.
Besides, it has the function of shock absorption and noice elimination.However, the defects of its thermolability and the hardness compare with iron are also obvious/.
10. Here is how plastic products are made.
Generally it starts from putting prepared plastic particles into the inlet of a machine.Second Inject the melt inside by injection or extrusion. Last step, get the finished products by producing through inner form inside of the machine. Although there are dozens of similar methods in this field,the most widely used are these injection & extrusion. In simpler terms, the advantages of plastic products include: low cost,easily molding and using, madifold usage,large demand and wide prospect.Please contact us if any plastic products wholesale is needed.
