This bowl-like equipment is the machine for grinding and shaking. When pouring the rough blank into the machine, the vibration of the machine results in rough blank ceaselessly collides and rubs with each other. During this process some small burrs in the edges will be broken and rubbed down. Turning off the machine, we can see the rough blank’s surface has becomesmoother after vibration compared with the previous condition.
There are many specific names for Lapel pins, for examples, lapel pin, cufflinks, hat clip and so on. So what determines the differences in naming? The answer is fittings. Different fittings lead to different usage of badges, thus, there are various name for Lapel pins.
Next procedure we are going to carry out is mounting fittings. Here what we installed are fittings of extensive use: blood pin and butterfly cap. At present there are two ways to install blood pin: one is to stick blood pin at the back of the products with glue. However, if we take this measure, blood pin is very likely to fall off with time because glue loses viscosity. We have chosen the better way, sliver soldering, to install blood pin. In this manner, the tightly welded blood pin becomes so solid that we cannot break it off even with great power, let along falling off because of the time.
After mounting fittings, next comes a very important operation: polishing. Polishing is a significant factor in determining the quality of Lapel pins. We believe no one is willing to see the badges he or she buys are rough around the edges or have scratched mark on the surface. Therefore, as a company which is highly responsible to clients, our requirements for polishing are very strict. The abrasive wheel used for polishing can be divided into many kinds: there are harder grinding wheel and softer cloth wheel. In a situation where the demand for surface finish and roughness is not high, we can conduct flat polish which means using grinding wheel to polish products directly. We need to use cloth wheel to polish for the purpose of surface finish and mirror gloss. Right now we use cloth wheel.
What we are doing now is the polish of Lapel pins’ surface. lapel pins will be polished one by one. Polishers carefully control how lapel pins touch with cloth wheel to make sure the polished surface is grinded down precisely. Cloth wheel itself is soft so the high-speed rotating cloth wheel can contact with Lapel pins’ surface to the fullest. It provides a better polishing quality as well as reducing the damage of badges to the minimum. We are going to do side polishing after finishing front polishing. Badges are still polished one by one, which is an inefficient way yet brings noticeable result. Soft fire makes sweet malt. Pure hand-made is always a synonym for high quality.
