THE MAIN POINTS OF PLASTIC CRATE MOULDING


How to make plastic crate? What is the plastic crate moulding process? What are the factors that influence the moulding cycle? The time required to complete an injection moulding process is called the cycle time, also known as the moulding cycle. The cycle time of plastic crate mould directly affects productivity.


The size accuracy and precision of the crates are affected by the time of holding pressure before the melting material is frozen at the gate. The holding time of the crate depends on the material temperature, mould temperature, the size of the main flow channel and the gate. If the dimensions and process conditions of the main channel and gate are normal, then the pressure value with the smallest fluctuation range of the crate shrinkage rate shall prevail. The cooling time of the crate mainly depends on the thickness of the crate, the thermal properties and crystallization properties of the plastic, as well as a series of factors such as mould temperature. At the end of the cooling time, plastic crates should be guaranteed to meet the requirements, and then demoulding. If the cooling time is too long, it will not only reduce production efficiency, but also cause difficulty in demoulding complex parts, and even demoulding stress will be generated during forced demoulding. Other factors affecting the moulding cycle include whether the moulding process is continuous and automated.


Therefore, in the plastic crate moulding process, should be in the premise of ensuring high quality, to shorten the moulding cycle of each stage of time. In the whole moulding cycle, injection time and cooling time are the most important, they have a decisive impact on the quality. The filling time in injection time is directly inversely proportional to the filling rate, and the filling time in production is generally about 3-5 seconds. The pressure holding time in the injection time is the pressure time on the plastic in the mould cavity, which accounts for a large proportion in the whole injection time.

 How to set your injection molding machine parameters? Injection Molding Machine Introduction Technology: Polycarbonate injection molding is an engineering technology that involves transforming plastic into useful and original products. Important process conditions for polycarbonate injection molding are temperature, pressure and corresponding individual time of action that affect plasticizing flow and cooling. Injection moulding machine setting – temperature control 1.  Barrel temperature : Temperature to be controlled during moulding process is barrel temperature, nozzle temperature and mold temperature. First two temperatures primarily affect plasticization and flow of plastic, while latter temperature primarily affects flow and cooling of plastic. Each plastic has a different flow temperature. Same plastic has different flow and decomposition temperatures due to different sources or grades. This is due to difference in average molecular weight and distr...

  What Is Plastic Injection Mold? A plastic injection tooling is a special type of manufacturing tool used for injection moulding. They are usually made of steel. Essentially, a plastic injection mold consists of a large cavity into which plastic is injected. This plastic flows around the core and the cavity, which have been built to create the proper size and shape of your component. Then, the plastic part solidifies on the mold, and is ejected from the mold once it’s hardened and solidified. Then, this process is repeated. A high-quality thermoplastic mold can be used to make millions of plastic components, and is a must-have if you are creating high-quality, high-volume injection-molded components. Plastic Injection Mold Terms If you are new to the world of injection moulding, there are some key terms you may want to know while working with an injection mold supplier. Injection mould This is a steel or aluminum mold that is used to injection mold plastic parts in a high-volume p...
