Plastic injection molding has actually changed the manufacturing world. Not only things have become easy, but also automated for accurate part production without serious defects. In order to obtain these highly accurate outcomes, manufacturers have to pay attention to the very beginning of mold shaping parts machining . The more accurate is the machining and tooling, the better the part outcome. Mold design Plastic injection mold has two basic components from the design aspect. The first is the cavity half of the mold, called A half; and the second is the ejector half of the mold, called B half.   These two halves have to work in conjunction to ensure better outcomes and hence machining has to be done accordingly. This is how the two halves work after machining: Molten plastic enters the molding machine through a sprue or gate, present on the A half. Once the molten resin enters, sprue bushing seals tightly against the nozzle of the injection barrel of the machine. This is ...

Blow molding is a method used for plastic manufacturing. The method provides the correct solution for various product design needs including plastic bottles for large scale productions. In order to ensure efficiency, it is essential for manufacturers to avoid common mistakes for blow mold and the molding process: Wrong plastic molding The most preferred plastic molding processes include blow molding and injection molding. Factors such as product requirements which include weight, shape, tolerance, and flexibility help choose the right molding process. Both the processes require different molds and machines, obviously. As expected, they have different economics which finalizing the design. Therefore, it is essential to choose the right mold design for final outcome. Individual costs being given the top priority The focus must be on the big picture. Delivering cost-effective solutions should be the top priority with any plastic molding process. Therefore, total cost of product...

Creating plastic parts having undercuts present distinctive challenges for molding operators. Undercuts represent recessions in a plastic part. These cuts make it difficult for the mold to slide away once the plastic part has been formed. These features prevent direct removal of the core, consequently making it essential to use an additional mold piece. A side core or internal core lifter can be used to form the desired shape. Custom core parts machining may be required for the process to get the core. Use of undercut designs These are used to create threaded parts, such as: Snap-on products like lipstick containers Screw-on bottle caps ·          And a variety of medical, automotive and consumer grade products Threaded bottle caps have complexities with the undercuts. After the formation of caps, the threads of the part and threads of the core get intermeshed. This intermesh has to be disengaged before pulling out of the core and the c...
