    What Products are Made from Injection Molding?

    Many plastic parts used in many products, so plastic parts is very popular, but nobody know how the plastic parts produce, in the fact, the plastic parts is made by plastic injection mold, the plastic parts is also called plastic injection molding or injection molding.   Injection moulding is used to create many things such as wire spools, packaging, bottle caps, automotive parts and components, pocket combs, some musical instruments (and parts of them), one-piece chairs and small tables, storage containers, mechanical parts (including gears), and most other plastic products.   PTMS is a china plastic injection mold company, we can make top quality plastic moulds as customers’ drawings or design, also we are china injection molding undercut manufacturer, for more details please visit web ptms-mold.com. We would like to share more and more injection molding knowledge with the worldwide people.

  • Injection Molding Defects
    Injection Molding Defects

    As a china injection molding exporter, PTMS always provide high quality custom plastic injection mold and custom moulding for the worldwide people, but at the first injection molding testing, there will be some defect plastic parts.   How the defected injection molding happened? Let us tell you some details, some defected parts is caused by injection mold flash, because some times injection molds have some a little flash, that is to say, molding flash occurs when a thin layer of material is forced out of the mold cavity at the parting line or ejector pins location. This excess material remains attached to the molded article, and normally has to be manually removed. Some reason as: worn or poorly fitting cavity or mold plates, Including, mold plate deformations and obstructions (grease, dirt, debris).   How to solve such problem? The mold making team must pay more attention to the injection mold making, besides, the engineer should have good solution for injection mold layout and other facts. PTMS has much experience in plastic injection mold making, for more details please visit our website ptms-mold.com, RFQ for project please send to sales@ptms-mold.com. 

  • Disadvantages of Injection Molding
    Disadvantages of Injection Molding

    Many people know the advantages of injection molding, such as fast production, low labor costs and etc, but do you know the disadvantages of injection molding? PTMS as a professional injection molding manufacturer in China, we have much experience in injection mold making and injection molding manufacturing, such as over injection molding, double color injection molding, injection molding with metal insert, etc.   So we would like to sharing some more advantages of injection molding for you, such as high-output production, multiple materials can be used at the same time, can be used to produce very small parts, reduced requirements for finishing, etc. The disadvantages of injection molding as: High initial tooling and machinery cost, Part design restrictions, Small runs of parts can be costly.   If you need high quality custom plastic injection molding, but you can't find a good plastic injection mold company, please do not hesitate to contact PTMS, we have much experience in plastic injection mold making and injection molding, for more please visit ptms-mold.com and RFQ send to sales@ptms-mold.com, thank you very much for your attention!   In the matter of the fact, there are many other advantages for injection molding, PTMS would like to discuss more about injection molding if you like, we can learn from each other, thanks for checking!

  • How Does Injection Molding Work?
    How Does Injection Molding Work?

    Plastic parts are widely used in many aspects, because it’s very easy to use and very safely and comfortable for people’s life, so plastic injection molding is very important for producing plastic parts, but just a little people know injection molding work, most do not know it, because just people who work in injection molding industry know it, so we will sharing this to you.   Material for the part is fed into a heated barrel, mixed, and forced into a mould cavity, where it cures and hardens to the configuration of the cavity. Moulds are typically made from metal, usually either steel or aluminium, and precision-machined to form the features of the part. They may need to split in a variety of ways to eject the finished part, or locate inserts that are bonded into the product. Most elastomeric thermoset polymers can be injection moulded, although custom compounding may be required in order to facilitate the process. Since 1995, looking across the entire range of thermoplastics, resins and thermoset types, the total number of available materials for injection moulding has increased dramatically at a rate of 750 per year. There were already approximately 18,000 materials available when that trend began, and injection moulding remains one of the most useful industrial processes ever invented.   PTMS as a professional plastic injection mold company in china, always provide customers custom plastic injection mold and custom injection molding, for more visit ptms-mold.com, PTMS would like to sharing other injection molding issue to people who are interested in plastic injection moulding, please give us feedback to sales@ptms-mold.com of some issue.
