The present invention the second purpose is in that to provide the manufacturing process of above-mentioned a kind of seamless table tennis.
The first step, makes bone, utilizes 3D printer to print the circular warp bone parallel by many and one-body molded formula elastomeric spherical skeleton that Duo Gen parallel bone forms,
Second step, spray webbing, utilize squash type spray webbing machine, the filament of hot melt state is sprayed and is set on above-mentioned skeleton, repeatedly spraying formation are attached to the fine and closely woven stratum reticulare that above-mentioned skeleton is outer and is connected with skeleton;
3rd step, spray epoxy glue, hot melt PVC sheet ultrasonic grinding is become ultra tiny PVC material powder, PUR powder and above-mentioned PVC material powder are mixed according to the volume ratio of 1:1-1:2, and the formation mixing glue that joins in common glue and stir, afterwards epoxy glue coating formation part are penetrated into transition epoxy glue in fine and closely woven stratum reticulare and connect layer;
4th step, condensation, the semi-finished product in the 3rd step are placed in condensation chamber and condense;
5th step, semi-finished product are placed into and hemispherical are closed up in the spherical shell mould formed by two, again through injection machine to the PVC material injecting molten condition between semi-finished product and spherical shell type mould, it is cooled into seamless spherical shell 3 afterwards, die sinking, deburring, can obtain having one-body molded and completely seamless table tennis.
Further, the injection hole of above-mentioned injection machine is at the end points up and down of above-mentioned spherical shell mould.
Further, above-mentioned injection machine injection temperature is 150-200 degree.
Further, the material of above-mentioned skeleton is high-temperature resistance plastice, and including LCP, above-mentioned high-temperature resistance plastice hot melting temperature is higher than above-mentioned PVC material hot melting temperature.
Further, the hot melting temperature of above-mentioned filament is more than or equal to above-mentioned PVC material hot melting temperature.
Beneficial effect
The seamless table tennis of one of invention offer and manufacturing process, table tennis manufacturing process compared to existing technology, present invention process step is few, manufactures quickly, it is possible to form completely seamless table tennis, there is skeleton simultaneously, effectively prevent table tennis from damaging in table tennis.
