The invention discloses a mess
tin forming process. The mess
tin forming process comprises the steps that S1, preheating is conducted, specifically, a plastic
raw material plate is fed into a preheating mechanism at first, the upper face and the
lower face of the plastic
raw material plate are heated so that the plastic
raw material plate can reach the pressing state, and the edges of the plastic raw material plate are not heated and adsorbed through a negative
pressure system; S2, pressing forming is conducted, specifically, the preheated material plate is fed into a mold set, the mold set is provided with a plurality of forming molds arranged sequentially, the mold pressing depths are gradually increased, and the preheated material plate is gradually pressed and formed; S3,
cutting is conducted, specifically, a mess
tin formed through pressing is fed into a
cutting mold, and excess materials of the mess tin formed through pressing are
cut off; and S4, collection is conducted, specifically, the mess tin of which the excess materials are
cut off is sucked away to be collected through a collection mechanism, and another negative
pressure system is used for adsorption during collection. The mess tin forming process has the beneficial effects that the yield is high, and cost is reduced.
