Abstract

The invention relates to an extrusion molding method for a POM (Polyoxymethylene) plate, which successively comprises the following steps of: 1. preparing before shaping: preparing materials and adjusting equipment; 2. plastifying and venting; 3. carrying out extrusion molding; 4. cutting a plate; 5. stacking the plates; and 6. baking. Compared with the prior art, the extrusion molding method has the beneficial effects that the materials do not need to be independently baked and processed before being plastified so as to simplify the production flow, improve the production efficiency, reduce equipment input and energy consumption and lower the production cost; the energy use ratio generated in the plastifying process is improved, energy waste is reduced, and the extrusion molding method conforms to the enterprise development mode of saving energy and protecting the environment; 3. a material preparation step and an equipment regulation step can be simultaneously carried out to improve the production speed and capacity and lower production cost.

Description

technical field [0001] The invention relates to the field of plastic extrusion molding, in particular to a POM plate extrusion molding method. Background technique [0002] Please refer to the existing POM board extrusion molding method figure 1 As shown, it includes the following steps in turn: 1. Mixing: mix the POM material and color masterbatch evenly in a certain proportion; 2. Adding materials: pour the mixed materials into the hopper; 3. Drying: through the large The high-power drying device dries the material; 4. Mold heating: heat each area of ​​the mold to the set temperature and keep the temperature constant for half an hour; 5. Barrel heating: heat each area of ​​the barrel to the set temperature and keep the temperature for half an hour; 6. , start the main engine, adjust the screw speed; 7. Plasticization: the mixed material enters the barrel through the hopper and is plasticized into a melt in the barrel; 8. Extrusion molding: the melt enters the mold cavity ...
