- Booling provides a wide range of material options to meet the needs of different product application scenarios
Application of 3D Blow Molding
3D blow molding technology has been widely used in the precision product production industry to meet the processing needs of various seamless pipes in the automotive, furniture, electrical appliances, construction, and other industries, such as turbocharged engine pipes, cooling system pipes, fuel lines, refueling pipes, natural gas pipelines, etc.
Guidelines for 3D Blow Molding
3D blow molding can realize the production of complex parts, reduce parting lines, improve wall thickness, obtain seamless products, and meet the processing requirements of precision products.
3D blow molding has technical advantages. The plastic raw materials are extruded and pre-blow molded, tightly adhered to one side wall of the mold, and the extruder or mold rotates the second or third axis according to the molding program preset by the Booling designer. After the intestine billet fills the mold cavity, the other side of the mold is closed and tightly fixed on the intestine billet segment, and separated from the subsequent billet segment. The entire billet is blown up and close to the mold cavity wall for cooling and solidification.
Types of 3D Blow Molding
Plastics are blown in the mold with the help of 3D movement to produce hollow products with complex structures, reduce surface burrs, reduce roughness, perform continuous extrusion, and eliminate the use of clamping devices.
- After the plastic blank is extruded, it is pre-blown and pressed against one side of the mold wall. The extruder head or mold rotates the second or third axis according to a pre-set program. When the intestinal blank fills the mold cavity, the other side of the mold is closed to separate the parison and the subsequent parts. After the mold is closed, compressed air is introduced, and the parison expands and presses against the inner surface of the mold. After solidification, a high-quality product is formed
- We provide negative pressure molding technology, making the upper and lower ends of the mold into sliders that can be opened and closed separately. By accurately controlling the injection volume and temperature, negative pressure is applied inside the mold to help the parison fit the inner wall of the mold more closely. This solution is more suitable for the molding of regular pipes
- Use a robot or manipulator to clamp and move the parison to enter the mold cavity more accurately. Booling processing has a high degree of automation and can be operated and clamped in a six-axis linkage mode to achieve more accurate parison position control
3D Blow Molding Molds
Booling provides the design and manufacture of extrusion, injection, stretching, and multi-layer blow molding molds to achieve the processing of products in different application scenarios.
- Extrusion Blow Molding Molds
During the 3D extrusion blow molding process, the parison can move in multiple dimensions. Booling provides 6-axis robots and manipulators for parison processing, which can improve accuracy and reduce flash. This method is suitable for the production of plastic bottles and other containers.
- Stretch Blow Molding Molds
Before the formal blow molding, the parison needs to be axially stretched to improve the mechanical properties of the final product, and then the stretched parison is blown.
- Injection Blow Molding Molds
Injection blow molding requires the use of an injection molding machine to inject molten plastic into the parison, and then blow it.
- Multi-layer Blow Molding Molds
Multi-layer blow molding molds can extrude plastic layers of multiple different materials at the same time, realizing the synchronous operation of multiple extruders, which is suitable for the production of large quantities of wide-mouth containers.
