The Hengxin Preform Mould has modular components that eliminate the need for hot runner replacements. It can accommodate any preform length with no tooling changes and can produce two to five moulds per minute. Low tooling costs make it an attractive option for any manufacturer. The moulding system can accommodate any number of cavities in one mold and is guaranteed to meet various customer requirements. This is one of the most cost-effective ways to produce custom-sized products.
The metal used in the production of PET preform moulds is S136 or 2316. Titanized steel is used to improve the hardness of preform mold components. The surface will have a golden colour. The mold can be hardened through vacuum quenching. Strip plates are usually made of alloy brass for high cooling efficiency. The Preform Mould can be made from materials like PC, PET, or PP.
The pin-valve type of hot-runner system is a great option for PET preforms. The heat-running system is efficient for reducing gate-trim costs. The dual heating and cooling system provides excellent quality control. The heater and nozzles are heated evenly through the entire cycle time. The heating band is imported from Germany. To ensure accuracy, the temperature of the hot-runner plate should be at least 2-5 microns.
Preform Moulds are manufactured with high-quality plastics. Typically, S136 or 2316 steel are used for the mold. These two types of steel can be cooled by vacuum and can reach 48-52HRC. The steel that is used for the Preform Mould must be compatible with the injection moulding machine. For example, a sparking machine can ensure a degree of accuracy of two to five microns.
The material used for the Preform Mould is important for the precision of the injection of plastics. Stainless steel is an excellent choice for plastic preform moulds. A quality Preform Mould will allow you to avoid mistakes and ensure that your products are consistently produced. You can use stainless steel, or a stainless steel preform mould. The choice of materials depends on the application and the material of the injection machine.
The Preform Mould can be made in two main ways: cold runner moulds and hot runner molds. Hot runner molds are the most popular option for making Preform Moulds. Both types have some drawbacks. First, the cold runner system is less likely to be automated than the hot runner system. Besides, the heavy moving plate of a PET preform mould can wear down the mechanical travel limiters and plate guide systems quickly.
In addition to steel, preform moulds are made from various types of steel. Some of these materials are made of alloys. Alloys such as S136 and 2316 are suitable for plastics. For example, S136 steel is used for the sliders and core inserts. It is possible to titanize these parts to reduce the NG (gas) visible in the finished product. The material used for the PET Preform Mould may also be of alloy brass.
The Preform Mould is made of steel. The barrels are designed for high-quality PET. The main material is steel. A typical PET preform mould is made of steel. The hot runner is made of steel. The plastic is heated at 300 degrees Celsius. The barrels should not be overheated for over fifteen minutes. If it is too hot, it will result in "white fog" and a non-plasticized product.
The PET Preform Mould is made in-house in one location. The design is based on the latest technological developments and in consultation with the European mould style. The machine has been tested to hold over 2.5 million injections. The NG is reduced with Moldflow analysis. The screw neck is made of premium nitride steel. The resulting product will be harder and more durable than the previous one. The preform mold has many advantages for both its user and the company.
The main components of a PET Preform Mould are made of stainless steel. The S136 material is used for the main component. The P20 mold base is made of German steel. Its material is welded and molded using the plate method. The resulting products are hard and light. The flexures in the molds are a part of the process. If the preforms are faulty, the final product will not be a quality product.
