Method for continuously forming plastic caps

A method for continuously forming plastic caps, comprising the following steps of:

• a. forming a first plastic cap strip in a mold by a first injection molding process, wherein the first plastic cap strip has a plurality of plastic caps and at least one connecting portion connected between every adjacent two of the plastic caps, the first plastic cap strip includes a first plastic cap at a forefront end thereof and a last plastic cap at a distal end thereof, and one end of the last plastic cap, away from the first plastic cap, has a first connecting portion extending downwardly, outwardly;
• b. pulling the first plastic cap strip outwardly after the mold is opened, wherein the mold has a mold cavity for forming the plastic caps and a clamping mold cavity located at a front end of the mold cavity, and the last plastic cap is in the clamping mod cavity and is covered by the clamping mod cavity when the mold is closed;
• c. forming a second plastic cap strip by a second injection molding process, wherein a first plastic cap at a forefront end of the second plastic cap strip extends outwardly to form a second connecting portion connected to the last plastic cap of the first plastic cap strip and an upper first connecting portion along an upper edge of the first connecting portion.
