Poly phenylene sulfide, abbreviated as PPS, is a new type of engineering plastic, which is mainly divided into two categories: one is a branched thermoplastic polymer with a high viscosity, and the other is a thermosetting polymer which has a linear molecular structure before curing, and can be softened to a certain extent if sufficiently … Read more
Flash, also known as flashing or burrs, mostly occurs between the matching parts of a mold, such as the parting surface of the mold, the sliding part of the slider, the clearance of the insert, and the gap of the ejector, etc. If the flashing is not resolved in a timely manner, it will be … Read more
A plastic injection mold is one of the most important tooling for injection molding, whose quality directly determines the quality of the final product. In the meantime, the mold cost takes up a great proportion in the production cost of an injection molder. If the injection mold life is short and the precision is not … Read more
This article is to analyze the engineering application scope, the respective characteristics of their applications and the application scope of HDPE, LDPE and LLDPE resin materials from the aspects of raw material, molecular structure, density, crystallinity, softening point, corrosion resistance, temperature range, mechanical properties, tensile strength, elongation at break, resistance to environmental stress cracking, industrial … Read more
The dents and hollows on the surface of a plastic product are referred to as “sink marks”. In addition to the appearance of the product, sink marks also affect the quality and strength of the final product. The reasons for sink marks are related to molding processing, mold design and the choice of the plastic … Read more
The cost of injection molding is influenced by a multitude of factors, but is mainly comprised of the following: Raw material cost – This cost is quite easy to be calculated. Ask the raw plastic material supplier how much 1kg costs, multiply the product weight by 3% of loss rate, and then multiply the raw … Read more
Study shows that 80% of the production cost is determined at the design stage. Therefore, the design stage is of great importance to product cost control. Rapid prototyping constitutes an important part in the industrial design process. From the fully manual prototyping (hand sampling) to the semi-mechanical prototyping, then to the modern 3D printing of … Read more
Many believes that the special-shaped cooling channel is not effective at all, but is a kind of deceptive technology! As a matter of fact, the point is not that the special-shaped cooling channel is not effective, but where you choose to place the cooling channel is still arguable. Let’s take a look at the example … Read more
PET PET Usually, this plastic is used in the production of plastic bottles, beverage bottles and the like. The plastic water bottles and carbonated beverage bottles people often buy are packaging products made from PET, which is a food-grade safe plastic material. Potential Risks: PET is only suitable for the packaging of room temperature or … Read more
The cost control of plastic injection molding also involves many factors. It must be controlled from the equipment, application process, raw material, as well as management and technology to achieve the optimal efficiency at the lowest cost. Tools and Components Control: Tools – All screws, nuts, nylon hoses and hose clamps, etc. in the packaging … Read more
