Plastic injection molding manufacturer today: Advantages of Blow Molding – The wall thickness of the blow molding product is uniform, the generated waste corners are small, and the weight difference is small, so it is more suitable for mass production of small blow molding products, and it is also suitable for the production of large-capacity blow molding barrels. Application of Blow Molding – Film blow molding is mainly used to manufacture plastic thin molds; Hollow blow molding is mainly used to make hollow plastic products bottles, packaging barrels, watering cans, fuel tanks, cans, toys and so on.

MULAN summarizes the defects of past products, and continuously improves them. The specifications of Precision mold can be customized according to your needs.
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.
Rotational molding can achieve very uniform wall thickness, and the corners will be thickened, which greatly enhances the strength and integrity of the product. Unlike blow molding, the corners will be pulled thin by pressure and cracked. , Affect the intensity. Rotational molding has also become rotomoulding. Rotational molding is a method in which thermoplastic plastics are rotated to form hollow plastic parts. The plastic raw material powder is added to the mold, and the mold is continuously rotated along two axes while heating. Under the action of gravity and thermal energy, the material presents a hollow plastic part with uniform wall thickness and complex structure.
Plastic overmolding metal: We use CNC machining/metal casting/sheet metal bending/sheet metal stamping on metal materials to pre-mold the designed substrate, and then wrap the plastic around the metal substrate at one time through overmolding, such as: pipe connectors , Electronic components, etc. Rubber overmolding metal: We use CNC machining/metal casting/sheet metal bending/sheet metal stamping on metal materials to pre-mold the designed substrate, and then wrap the rubber material on the surface of the metal substrate through overmolding to present a soft rubber layer. Such as fitness equipment, medical supplies, hammer handles, children’s toys, etc. Discover a lot more information on china-plasticparts.com.
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.
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.
