The way of cavity and core part ejecting
For such kind of water jug, there is a flower shape in the bottom part, so for ejecting, need to pay attention to make sliders to ensure the production smoothly.
The outer and inner shape of the plastic part is directly formed by the cavity and the core. This complicated three-dimensional surface processing is more difficult, especially the blind hole type inner molding surface processing of the cavity, if the traditional processing method is used, Workers are required to have a high technical level, many auxiliary fixtures, many tools, and long processing cycles.
The ejector is an important factor affecting the deformation and dimensional accuracy of the product. Therefore, the best ejector point should be selected to make the mold release evenly. Most of the high-precision injection molds are inlaid or fully assembled in the structure, which requires the processing precision and interchangeability of the mold parts to be greatly improved.
Can you use the recycled PP material to produce the water jug?
In general, the production of water jug uses PP new materials. The real PP is tasteless. PP can be used for food contact food products because PP has excellent molding properties and can be made into products without adding any processing aids, avoiding problems such as plasticizers and hormones. So it is very likely that you are not using a real pure PP water bottle.
The source of recycled PP materials is unknown (garbage, waste products, factory mouth water, waste), mixed with other plastics, and volatilized by small molecules of heat to produce odor. At the same time, it is also mixed with toxic substances such as heavy metals, organic dyes, cyanide, and so on.
Therefore, you must not use the recycled material.
