Surface finish of plastic injection molding product
Different physical and chemical properties of the polymer blends, as well as the different parameters of the plastic injection molding process cause the surface finish on the plastic composites to vary greatly. For a plastic injection molding service provider that offers custom-made products, the first goal is to work in collaboration with the client to determine the importance of surface finish for the exterior appearance, as well as the performance of the injection molded product, or to be specific, is the final product an eye-catching piece or simply a functional one? Your answer to this question determines the choice of material and the option of surface finish, based on which the plastic injection molding process is set, and the secondary finishing operations … Read more

Quests to know the plastic injection mold price?
Do you have engineering design or physic samples? if you provide drawing, the most mold factories prefer 3D data in step or IGES format. If the design is complicated or large, the mold design should also be complicated and more cost. if you have physical samples, the mold factory will copy it and made the mold for you. What kind of plastic materials will you use for product? their price and characters are totally different when you choose different plastic resins. How many cavities will the injection mold have? how many parts will it make per shot(cycle)?it depends on the quantity you forcast to produce. if you plan to produce a huge quantity, then need more cavities in the mold. … Read more
Factors Affect Plastic Injection Molding Cost
The involvement in a plastic injection molding project will surely enable you to understand that the mold can easily become the most expensive part in a project. Among the multiple factors that affect the cost of a plastic injection molding product, the top three ones are undoubtedly the dimensions and complexity of the part, the quantity of the part, as well as the effort required to build the plastic injection mold. As we know, the cost of all manufactured products is dependent on that of the raw material and the labor required. Therefore, the cost of a plastic injection molding product is also dependent on the costs of the plastic material and the labor involved throughout the production process. Here, … Read more
How to choose cost effective plastic injection molding supplier from China?
What kind of injection molding supplier is a better choice? With regard to this question, people believe that it depends on the specific situation. When considered from the only perspective of factory size, it is better that you choose the larger one, because a large size is often an synonym of strength, meaning that the comprehensive strength of the factory is better. Besides, the size also indirectly reflects how popular the factory is among customers! However, conversely, the larger the size, the higher the management cost is, so there will not be noticeable cost advantages. It is very important to know whether the injection molding supplier you choose regards you as an important customer, i.e., whether you are important to them. If … Read more
Polycarbonates(PC) injection molding properties and conditions
What is the PC injection molding material? Polycarbonates, more commonly known as PC, are a group of thermoplastic polymers containing carbonate groups in their chemical structures. Although PC are commercially available in a diversity of different of colors (either translucent or opaque), the raw material is able to transmit light internally in a capacity similar to that of glass. The PC material is typically applied to produce a wide range of materials and are especially useful when the product requires outstanding resistance to impact and / or good transparency (for example, when used in production of bullet-proof glass). The PC material is most commonly applied for production of plastic lenses in eyewear, medical equipment, plastic auto components / parts, protective gears, … Read more
POM injection molding properties and conditions
What is the POM injection molding plastic material? Polyoxymethylene (POM), also known as acetal, polyacetal, and polyformaldehyde, is a naturally white semi-crystalline engineering thermoplastic used in production of precision parts that require high stiffness, low friction, excellent dimensional stability, as well as high resistance to abrasion, heat, water absorption and organic chemical compounds, such as hydrocarbons. It is a plastic material featuring a very high tensile strength, with an outstanding resistance to creep, allowing it to bridge the gaps of material properties between most of the plastics and metals. Typically, the applications of POM include small size gears, home electronics, molded plastic zippers, medical equipment, and components of furniture like the plastic feet of a couch. Why is POM so … Read more
Nylon(PA) injection molding properties and conditions
What Is the Nylon Material, and What Are Its Purposes? Nylon plastic injection molding material can be used in a great diversity of application projects, including clothing, rubber material reinforcement such as car tires, applications as a rope or a thread, as well as a great number of plastic injection molded vehicle parts and mechanical equipment. It is especially strong, resistant to abrasions, moisture absorption and chemicals, as well as durable, elastic and easy to clean. Nylon is able to be used to replace the low strength metal materials. By virtue of its strength, temperature resilience and chemical compatibility, it is the ideal plastic material for production of vehicle engine components. The Nylon plastic injection molding is also able to be … Read more
Polypropylene Injection Molding: Properties and Conditions
What Is the Polypropylene (PP) injection molding Material ? Polypropylene/PP injection molding material is a plastic polymer made by combining several propylene monomers. It is widely used in food containers due to its safety, as it is free from BPA. This thermoplastic polymer features a wide range of applications that include packaging of consumer products, plastic components for such industries as the automotive industry. Relatively speaking, the surface of the PP plastic is very slippery, so in some low-friction applications, it can be used to replace some plastics like polyacetal (POM), or used as a contact point for furniture. One of the weaknesses of this property might be that it is not easy to adhere PP to the surface of … Read more
