It causes, will also result in corrugation, should check and replace immediately the quartz ampoule of damage.
As a kind of preferred embodiment of the present invention, in step d, further include and be placed in the PPSU material sheets after heating and softening
Between mold and lower mold, mold is pushed close to PPSU material sheets, until at a distance of 4.5mm when stops pushing, lower die at this time
Tool starts lifting upwards, and opens vaccum-pumping equipment simultaneously, and lower mold is raised to after its bottom is adjacent to mold, stops lifting,
Lower mold starts to be raised to the whole process of stopping, and the draught head formed by PPSU material sheets upper and lower surface is by PPSU materials
Sheet material stretching deforms, and is covered on the contoured surface of lower mold, shape needed for formation.
As a kind of preferred embodiment of the present invention, in step e, cooled down using the method for Physical temperature-lowering, the physics
Cooling refers to spray 5-10 DEG C of cold water, while open wind turbine to plastics by PPSU material piece of the spray gun after shape needed for formation
PPSU material pieces blow room temperature wind, and the Physical temperature-lowering time is 20-40 seconds.
As a kind of preferred embodiment of the present invention, the mold is integrally set as wolfram steel material.
PPSU slabs plastics sucking moulding method of the present invention particularly produces the thin PPSU slabs of some walls, according to injection work
Skill, the plastics that heat is melted are not easy to flow to the position compared with periphery, and shape is relatively simple, low production efficiency, and the present invention is used to inhale
Modeling technique, PPSU slabs can be quickly molded in a mold, and shaping speed is fast, and production efficiency is high, and manufacture craft is more simple, be given up
Product rate is low, and the PPSU thick blanks handles of plastics sucking moulding are less, and waste of material is few, reduces production cost, and manufacture the requirement of mold
Low, the expense of the various aspects such as repair, maintenance of mold is equally relatively low, suitable for promoting.
