What is the difference between an extrusion molded hollow board and an injection molded hollow board? I recently discovered that most people still don't know this question. Mindwell engineers will bring you the answer.
What is the difference between an extrusion molded hollow board and an injection molded hollow board?
Extrusion molded hollow board is the most common one in the current market. The characteristic of this production method is that the production process is extremely continuous, and it can also be extruded according to the needs of any length and any specifications. The production efficiency is very high. The production of the mold is also very simple, the size can be accurately controlled, the manufacturing and maintenance are also very convenient, the investment is small, the effect is fast, and the applicability is wide. Various materials and specifications of different specifications can be manufactured from this Hollow board sheet.
Because of the high investment cost, injection-molded hollow plates do not often appear in the market. This production method is characterized by injection molding of hollow plate products with various shapes and complex shapes, and the molded structure dimensions are relatively accurate, and the surface quality Excellent, can realize standardization, standardization, and serialization. The disadvantage is that the investment cost is high, and the manufacturing cost of the mold is high.
The above is the difference between the hollow plate made by extrusion molding and the hollow plate made by injection molding.
