Rectifier manufacturing method and die for manufacturing rectifier

Abstract

The invention relates to a rectifier, in particular to a rectifier manufacturing method and a die for manufacturing a rectifier. The manufacturing method comprises the following steps: providing a matrix and a die body, wherein the die body has a mark part used for marking a cutting position of the matrix; heating the matrix to soften the matrix; placing the softened matrix on the die body for moulding, wherein after moulding, the mark part of the matrix corresponding to the die body forms a mark line; cooling the matrix till the matrix is hardened; separating the matrix from the die body; and cutting the matrix along the mark line to obtain the rectifier. Compared with prior art, since after moulding of the matrix, the mark line matched with the mark part is formed, such that when a worker cuts the matrix, the worker can directly cut along the mark line of the matrix, such that the cutting work of the matrix can be finished at one step, a dental crown part of the matrix is not damaged while the manufacturing time of the rectifier is effectively reduced, therefore, the comfortable level during wearing of a user is improved.

Description

technical field [0001] The invention relates to an orthotic, in particular to a manufacturing method of the orthotic and a mold for making the orthotic. Background technique [0002] Orthodontic appliances, as a tool for correcting the alignment of teeth, have been widely used. [0003] At the same time, the current existing aligners are generally made of resin molds, and generally the resin molds are first laminated when making, and the excess resin molds are cut off after compression molding, and then Made by grinding the cutting position. However, when cutting and polishing the appliance, most of them are cut along the gingival margin after the resin mold is laminated by the workers based on their experience, which often results in over-cutting, over-grinding or under-cutting of the resin mold. And when there is excessive cutting and grinding of the resin mold, it will easily damage the crown part of the resin mold, which will not only affect the appearance of the appli...

AI Technical Summary

Problems solved by technology

However, when cutting and polishing the aligner, most of the workers cut along the gingival margin after the resin mold is laminated based on experience, so it often results in over-cutting, over-grinding or under-cutting of the resin mold.

However, when there is excessive cutting and grinding of the resin mold, it will easily damage the crown part of the resin mold, which will not only affect the appearance of the appliance, but also affect the comfort of the user when wearing the appliance.

And when there is less cutting of the resin mold, it is often necessary to cut and polish the resin mold again, which will prolong the production time of the appliance
