Excellent blow molding company supplier
Excellent injection mold wholesale manufacturer: Film blow molding: the molten plastic is extruded from the circular gap of the extruder head mouth die in a cylindrical thin tube, while the compressed air is blown into the thin tube cavity from the center hole of the head, the thin tube is blown into a larger diameter tubular film, and then rolled up after cooling. Hollow blow molding: With the help of gas pressure, the rubber type blank closed in the mold cavity is blown into a secondary molding technology of hollow products, is the production of hollow plastic products. The manufacturing methods of hollow blow molding are different, including extrusion blow molding, injection blow molding and stretch blow molding.

Blow molding will be more cost-effective than injection and rotational molding. Generally speaking, the production cost of a product needs to refer to several factors, such as part structure design, product quantity, product material selection, and product application functionality. After a comprehensive analysis, we choose the most reasonable cost manufacturing process. Blow molding materials are relatively small, but for hollow structure parts, the structure is not complicated. When mass production is required, blow molding must be cheaper and more efficient than other plastic molding processes. Compression molding composite parts can often replace the application of metal parts, provide similar strength and mechanical properties, and have the characteristics of light weight, corrosion resistance, insulation, etc., and can reduce the complex shape created by secondary processing.
Rotomolding molds are usually made of cast aluminum or steel plates without the aid of high pressure, so the mold process is relatively simple, the cost is low, and small batch production has economic advantages and is suitable for early investment in product development. Rotomolding relies on the material to adhere to the inner wall of the mold, which has very low restrictions on the shape of the product. It can be achieved smoothly through reasonable design of the mold details. And you can easily create functions such as reinforced ribs, custom textures, and in-mold inlays.
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.
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.
