An injection plastic mold is a tool made up of a series of parts that shape and cool molten plastic to create discrete part shapes. The injection mold is divided into many parts, the common parts are: (1) splint   The mold halves are connected to the forming platen by means of clamping plates. Die clamps use large bolts to hold them in place; other machines use magnets to...

   A critical but sometimes overlooked injection plastic mold design consideration concerns the correct mold material selection. Because the choice of mold material will affect the tool life.    The right steel grade and hardness can properly balance wear and toughness so tool components that run together do not wear out prematurely. The hardness of the steel also...

   As an important part of the mold production process, the function of the guide post and guide bush is to guide, position, bear the lateral pressure and support the weight of the mold. The guiding function is to ensure that in the process of moving mold and fixed mold, normal alignment can be ensured, so as to prevent the mold from being out of place, losing the most basic...

　The tension and compression springs are actually located on opposite sides of the spring range. Tension springs are mainly used to fix two components together, and Plastic Compression Springs are best suited to keep the components from touching from the beginning. Both use coil design to improve elasticity and strength, but they work under two different principles of elastic potential energy....

　　1. The primary maintenance of the Injection plastic mold is carried out by the production operator. The main contents of maintenance are cleaning, lubrication, and inspection. 　　2. The secondary maintenance work of the mold is completed by the mold repair personnel, and records are made according to the maintenance situation. The main content of secondary maintenance: 　　a. Polish the rounded...

Some other common materials used for Injection plastic mold include polycarbonate, nylon, acrylic, and polyoxymethylene. Each of these materials have their advantages and disadvantages, which is why, when determining which material to work with, you need to think of how the final product will be used. Will it need to be food-safe? Does it need to be heat tolerant? UV resistant? These are some...

Applying a Sufficient Ejection Surface AreaA plastic part’s size and geometry play a large role in determining the ejection surface area. If the area is insufficient, it can result in part deformities, breakage, and longer cycle times. The best practice of Injection plastic mold is to lean towards using larger ejection surface areas when prototyping. If your part has smaller ejection...

Have you ever had an Injection plastic mold part that didn’t live up to its’ use in the environment for which it was intended? After several attempts to correct the problems did you give up and choose a metal instead? Would it surprise you to know that many plastic parts don’t make it to market with the part properties originally intended? Did you ever ask yourself what...

It’s not uncommon for a small plastic injection Mold parts to be expected to hold up under a large load. One of the ways to strengthen a part is by adding one or more “ribs” to the design. Ribs are thin protrusions that extend perpendicular from a wall or plane to provide added stiffness and strength. Designers commonly try to increase the strength of a part by making its...

Automation is becoming increasingly prevalent throughout every type of manufacturing because automated systems can take on most aspects of the work without operator action. This results in: Better utilization of the machines. Automated systems of Injection plastic mold are interconnected and communicate through a centralized control system. This type of injection molding equipment will generate...
