Factors that influence the pipe fitting mould quality
The manufacturing process of the pipe fitting mould is also an important part of ensuring the quality of the pipe fitting mould. The processing method and processing accuracy in the pipe fitting mould manufacturing process will also affect the service life of the mould. The accuracy of each part directly affects the overall assembly of the pipe mould. In addition to the influence of the accuracy of the equipment itself, it is necessary to improve the processing accuracy of the pipe mould parts by improving the processing method of the parts; If the overall assembly effect of the mould does not meet the requirements, it will have a great impact on the overall quality of the mould. Pipe fitting moulds have many different mould structures. The screws inside this foldable core system unscrew the system, using slides outside the screw. There are many ways to drive the foldable core system-hydraulic cylinder, hydraulic motor, angle pin, guide groove. The core that we have made foldable in minutes is 32 mm in diameter.
Insert moulding process
The insert molding shares the same process used in conventional injection molding - melt and extrude solid pellets of raw materials into a mold, solidify the plastic, then open the press and eject the molded parts.
Compared with conventional injection molding, the insert molding process utilizes the same materials. Engineered thermoplastics are applied for extremely high heat molding. Because of their enhanced electrical, physical and chemical properties, the materials are strong enough to stand up to extremely high temperatures and the components are able to resist very severe conditions.
Before a material is injected into the mold, place the insert in the mold by hand or automation, and then, as the material moves into undercut features of the insert, the insert is therefore perfectly secured as if it were previously integrated into the molded component.
There are some injection molding producers who employ vertical/vertical injection molding presses, taking advantage of gravity to facilitate the insert molding process, because this helps keep the insert in position when the mold is closing.
The majority of vertical presses utilize multiple bottom mold halves to mate with a single top. By doing so, while one of the bottom halves is molding with the involvement of the top half, the other bottoms are available to be filled with inserts.
The application of multiple bottom halves allows inserts to be loaded into one bottom while the others are molding, therefore press time is substantially shortened.
