So knowing what are the screw slippage reasons and treatment of injection molding machines is very important for every plastic injection moulding engineer and factory or workshop manager. When the injection screw is difficult to press the material at the feeding port, or the length of the barrel cannot form enough adhesion to convey the material, then the screw will slip. In the stage of screw pre-molding, when the screw rotates in the barrel to convey the material along the direction of the screw and retreats to accumulate the material for the next injection, the screw will also slip. If the screw starts to slip during the pre-molding phase, the axial movement

With various molds available, it is essential to understand the basics of each kind to make an informed decision about which type of mold is right for your project. Pipe fitting molds fall under three categories: extrusion, die casting, and forging. Extrusion molds, made from metals, plastics, and composites, are typically used to create smaller pipe fittings such as elbows, tees, and reducers. Die casting molds, made from metals, generate larger pipe fittings like flanges and couplings. Forging molds, also made from metals, create the most common type of pipe fitting. Each type of mold has its own set of benefits and drawbacks. Extrusion
Read more →Injection molding is a manufacturing process used to produce a wide range of plastic products, from small components to large containers and automotive parts. The process involves melting plastic pellets and injecting them into a mold cavity, where they cool and solidify into the desired shape. Injection molding machines are used to automate this process and are typically large, heavy-duty machines that can produce a high volume of products. There are several types of injection molding machines, including hydraulic, electric, and hybrid machines. Hydraulic machines are the most common and use hydraulic pumps to operate the machine’s movements, including the clamping, injection, and ejection processes. Electric machines use electric motors and servo motors to operate the machine’s movements and are more energy-efficient. Hybrid machines combine hydraulic and electric
Read more →Projection area in plastic injection molding is a method used in injection molding to determine the clamping force required to hold the mold closed during the injection process. The projected area is the area of the part perpendicular to the direction of the clamping force, and it is used to calculate the force needed to keep the mold closed as the molten plastic is injected into the mold. During the injection molding process, the molten plastic is injected into a mold cavity under high pressure. The mold is held closed by a clamping unit that applies a force to keep the two halves of the mold together. The amount of force required to hold the mold closed is determined by the projected area of the part being molded
Read more →What is projected area in plastic injection molding The total projection area is determined by adding up the projected areas of the cavities and runners in relation to the parting surface. As such, this value is subject to variation based on the number of items being molded and the layout of the runners. It is important to keep these factors in mind when calculating the total projection area. Below is the guide for how to calculate the projected area for injection molding. This process is crucial for ensuring that the mold can be properly created and that the final product meets the necessary specifications or help you to pick the right injection molding machines for the mold in production. Step 1: Determine the parting line of the mold.

Why we need to set mold protection to prevent damage? Beside the injection molding machine itself, the second most expensive piece of equipment we use on a daily basis is the mold. If the molds are damaged, you are not only responsible for the cost of maintenance, but also for downtime and labor costs.If done correctly, the mold can rest on something as thin as a business card. Here are three key components for setting up mold protection on injection molding machines: 1. Starting position of mold protection When do you reach the point in the mold where you might break when the mold is closed? In the figure above, this point is when the mold touches the guide pin.
