1, PE, PP, PVC, GPPS, PMMA, SAN, PC, PBT, dyeing opaque color, titanium dioxide may be added.
2, PVC, GPPS, SAN, PMMA, PC dyed transparent or pearl color, can not add titanium white, lithopone, or other inorganic substances.
3。 In PE, PP, PVC, using a variety of color agent, need to pay attention to different levels of transfer phenomenon, when the choice need to pay attention to.
4。 Due to the A (ABS and SAN Propylene) Components, green amino ( - CN) Can lead to color is not ideal, Color is not stable, not bright) , on the other hand, A component can increase the viscosity of the melt and the friction shear heat, so demand higher heat resistance of toner.
5。 Because of PMMA and PC containing ester hydrolysis, mixed color after completely dry before shaping.
6, PA contains strong polarity of amino, water imbibition is strong, also should be thoroughly before mixed color formed after baking.
7。 Because of the polyvinyl chloride, Especially the soft polyvinyl chloride) Contains a lot of plastic agent and additives including heat stabilizer can make bright coloring sex difference, the analysis of additives can easily lead to leakage and mobile agent. In addition, PVC injection mould c in the heat decomposition of hydrogen chloride ( HCL) Will also change the color of the toner.
in order to satisfy the human pursuit of material, the industry constantly improve the product's performance, product made up of parts, product parts is more and more precision, product parts to the size of the original design.
injection processing industry, precision injection processing has become a major outstanding injection enterprise competition in the field.
now many products actually reach the life of the original design, there are many reasons.
one of the reasons is the size of the product parts cannot meet the original design, complete product consists of several parts to tens of thousands of parts, size can not meet the design requirements, the use of a problem, or even longer, replacement parts, such as all parts of the spacecraft are thousands to choose all
as a result, in recent years, various industries increased precision manufacturing, who can master precision manufacturing technology, the injection processing who can dominate in the future competition.
in recent years, the injection precision injection processing industry has developed rapidly, but meet precision injection processing conditions generally need what aspects?
is an advanced injection molding machine equipment, injection molding machine as the basis of injection molding, if the foundation is bad, can't produce good product.
second, mold manufacturing, injection mold cannot leave the industry, good performance of the mold for the high precision injection can increase a lot of points.
third, injection workers without good injection engineer, better equipment.
4: the purchase of raw materials, the same plastic, its technology is different, the performance of the plastic is different also.
affect product has the variety of plastic molding injection pressure are required, the types of injection molding machine, nozzle form, the product shape complexity and injection system, etc. , determine product forming method of the injection pressure with analogy method, data refer to all kinds of plastic injection molding technology, the common product molding injection pressure is 70 ~ 150 mpa, the injection mold simulation computer software to calculate the injection molding process, injection pressure prediction.
