Quality injection mold wholesale factory: Blow molding products are a rapidly developing plastic products. After the 1950s, with the birth of high-density polyethylene and the development of blow molding machines, blow molding technology has been widely used. The volume of hollow containers can reach thousands of liters, and some production has been controlled by computers. The plastics suitable for blow molding are polyethylene, polyvinyl chloride, polypropylene, polyester, etc., which are widely used in industrial packaging containers. Mulan Group uses advanced processing equipment and scientific quality management system to provide global suppliers with one-stop customized plastic and metal custom parts production solutions. Mulan Group provides a cost-effective one-stop supply service with an efficient sales team, reasonable low-cost quotation and strong manufacturing resources.

As a custom mould manufacturer, We will make a rapid prototype for you, which will help you analyze and review your product design, and help you improve and adjust the product design to conform to the actual manufacturing process. When the product is in the mold, it is relatively soft at high temperature, and the unreasonable ejection method will leave a mark on the surface of the product. This problem is irreversible, but the defect can be compensated by hiding and reducing the cross-section of the ejector pin. Mulan Group Very good at solving such problems.
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 mainly relies on sheet metal bending and other manufacturing processes to apply V-shaped and U-shaped pressure to metal sheets to create three-dimensional product prototypes, and cut, emboss, and link through processes such as laser cutting, sheet metal stamping, and metal welding. It can meet the needs of various industries such as shells, brackets, cabinets, boxes and other products. Relying on the characteristics of fast turnover and low cost efficiency, it is widely used in: medical, automobile manufacturing, aerospace, military, household hardware and other industries.
Overmolding process is a unique injection molding process. After injection molding the internal base material (usually metal and plastic materials with higher hardness), it is placed in overmolding molds for molding and cooling. When the injection molding parts you need to take into account the characteristics of sturdiness, practicality, beauty, etc., you must consider using injection overmolding. This is an efficient and cost-effective molding process, suitable for multifunctional injection molding solutions in all walks of life.

The process of rotational molding is much simpler than the manufacturing process that relies on pressure molding, but in fact it requires very rich experience and technical knowledge. While the material cannot be controlled by high pressure, the environmental temperature, environmental humidity, mold type, material specification, material Factors such as pretreatment quality will directly affect the final quality of rotomolding products. Put the powdered plastic into the hollow mold. Close the mold and rotate along the two axes. Heating the mold during the rotation process to melt the powder material. After all the materials are melted, cool the mold.After the product has solidified, open the mold and take out the product.
Place the thermoset plastic material in the compression molds cavity, melt the thermoset material by heating, close the mold with pressure, and the melted thermoset material will instantly fill the entire cavity under the action of pressure. In this process, it is very important to control the weight, shape, and specifications of solid materials, which will directly affect product quality. Thermosetting materials will reach the best curing state under the control of stable high pressure and high temperature. Compression molding parts are ejected, and the remaining materials are cleaned manually or by using cutting molds.
