Excellent blow mold manufacturer and supplier: Stretch blow molding is the process method of billet, stretch and blow molding in a machine. Billet is a semi-finished product in the production process. After cooling, cold billet is reheated to stretch and blow molding. After extrusion molding, directional tensile blow molding, maintain a certain tensile speed, orientation before blowing, after stretching, transparency, impact strength, hardness and rigidity, surface gloss and barrier properties have been higher. The production process of stretch blow molding is to control the temperature of the billet below the melting point under the principle of bidirectional bigeneration to improve the strength of the product.

Our team of mold experts will write precision machining programs according to the design of the product, and have a very efficient and fast response. All accessories are provided by excellent suppliers, and the material report and physical performance report can transparently confirm that the mold has high-quality manufacturing capabilities. Reliable DFM is the key to our project. Because all processes are completed under our supervision, the DMF report is very credible and reliable. Relying on the uninterrupted sampling and testing by quality inspectors, the results of the first batch of samples will be quickly obtained, and the change trajectory of the product under different parameters will be recorded in detail. In order to inform you of the actual operation manual. Finally, we will send you all the test samples, and you will understand our test content, because you believe in Mulan Group, so you need to understand these processes more than we do.
Blow molding is a process in which a hollow product formed by the expansion of a hot-melt plastic tube closed in a mold by means of gas pressure. The blow molding process was used to produce LDPE vials in World War II. In the 1950s, with the birth of HDPE materials and the development of blow molding machines, the blow molding process was widely used and the technology was upgraded. According to the different plastic blank tubes, it can be divided into extrusion blow molding, injection blow molding, stretch blow molding and multi-layer blow molding. Compression molding process A manufacturing process for molding polymers such as thermosetting plastics, thermoplastics, elastomers, rubber and plastic materials, and natural rubber. For example: children’s pacifiers, sealing rubber rings, power insulation parts, electrical enclosures, etc.
Sheet metal prototype is a method to quickly create design details of metal parts through manufacturing processes such as cutting, bending, stamping, and stretching of metal plates. In this process, it will try to use as little mold investment as possible. It is widely used in the development and research phase of metal products to help customers test product functionality and design rationality. More often, we rely on sheet metal prototype to provide metal inserts for the plastic molding process of in-mold molding, and the prototype can be produced within a few hours.
Rigid plastic overmolding process: After the internal base material is made of rigid plastic injection molding, another type of steel plastic is wrapped around the base material through an overmolding mold. The color of the material can be customized, but the material compatibility limit should be consulted. Otherwise, cavities or cracks will occur. Rubber overmolding plastic: The internal base material is made of steel plastic. After molding, the rubber material or TPE material is wrapped on the surface of the base material. The product presents the softness of rubber and can play a role in wear resistance and non-slip, such as: toothbrush handles, electric tool handles, etc. Discover extra info on https://www.china-plasticparts.com/.
Rotomolding products & mold design: We provide customers with professional rotomolding design technical support services, mainly focusing on the design of rotomolding molds. We use our rich experience to reduce quality risks in the design and ensure the high quality of products as you expect , And reduce the cost of mold modification due to design errors. In-house Mold Manufacturing: We have a powerful rotational molding mold manufacturing center, three 5-meter-long CNC machining centers, which can accurately engrave the details of the mold. Usually we will use high-quality aluminum alloy or cast aluminum to make rotomolding molds. High-quality mold manufacturing ensures that you can receive the highest quality products in the shortest time and have economic benefits. And we can add custom textures, logos, batch numbers and other copywriting on the surface of the mold.
The loss of raw materials is small and will not cause too much loss (usually 2% to 5% of the product quality). The internal stress of the product is very low, and the warpage deformation is also very small, and the mechanical properties are relatively stable. The wear of the mold cavity is small, and the maintenance cost of the mold is low. The cost of molding equipment is low, and the mold structure is simpler, and the manufacturing cost is usually lower than that of injection molds or transfer molding molds. Larger flat products can be formed. The size of the products that can be formed by molding is only determined by the clamping force of the existing molding press and the size of the template.
