Drilling-resistant lock cylinder and manufacturing method
A method of forming a lock cylinder plug using metal injection molding includes injecting a material having a metal component and a plastic component into a mold. The metal component of the material is at least partially steel. The method includes molding the material into a lock cylinder plug having a keyway passage. The method includes degreasing the lock cylinder plug and supporting a portion of the lock cylinder plug using at least one ceramic support prior to increasing the density of the lock cylinder plug by performing a sintering heat treatment. The method includes inspecting the lock cylinder by inserting a keyway portion of a keyway gauge into a keyway passage of the lock cylinder plug. The inspection further includes classifying the cylinder plug as acceptable, at least in part, if the keyway portion of the keyway gauge can be fully inserted into the keyway passage.
一种使用金属注射模制来形成锁芯插塞的方法，该方法包括将具有金属成分和塑料成分的材料注射到模具中。该材料的金属成分至少部分地是钢。该方法包括将该材料模制成具有钥匙槽通路的锁芯插塞。该方法包括在通过执行烧结加热处理增加锁芯插塞的密度之前，对锁芯插塞进行脱脂并使用至少一个陶瓷支承件支承锁芯插塞的一部分。该方法包括通过将钥匙槽量规的钥匙槽部分插入到锁芯插塞的钥匙槽通路中来检查锁芯。检查还包括，至少部分地在钥匙槽量规的钥匙槽部分能够完全插入到钥匙槽通路内的情况下，将锁芯插塞分类为可接受的。
