The application of CNC machining or SLA laser rapid prototyping manufacturing prototype, that is, turning over the hand board, so that it has a clear view and understanding of its construction and appearance, then, before the manufacture of silicone moulds, we need to understand its shape and structure. That is, to understand its prototype, the use of silicone moulds in hand board factories can make more than 20 similar products.

The processing and manufacturing method of hand board

CNC hand board is a more common and commonly used hand, not only because of its mature technology, a part of its material is very special, such as silicone, the price of this material is not very expensive, but the quality is very guaranteed, then it is a complex introduction to you. Silicone hand I this is one of the ways to manufacture hand board.

The advantages of the silicone board secondary focus on the consumption of work fast, low cost, high failure rate, we should do what do not have to worry, the manufacture of hand board tips you, you can use CNC CNC machining or SLA laser rapid prototyping manufacturing prototype, that is, turn over a hand board, then its structure and appearance will have a clear view and understanding. e mold, we need to understand its shape and structure, that is, to Understand its prototype, the use of hand board factory silicone moulds can make more than 20 similar products.

The fixed nature of the hand board factory SLA material invites the high precision and efficiency of equipment that can only be made from certain specific products

The advantage of the hand board factory SLA hand board is quickly formed, ordinary products if CNC processing, then the work required for dozens of hours, the next machine will require manual bonding, grinding and other processes, a total of 2-3 days, and as SLA, it is not affected by the complexity of the product S. The construction, which can be composed as a whole, the product is a whole, saving the work and cost of subsequent manual grinding and attachment, etc. The process saves a small amount of process, and high precision, now SLA speed forming machine precision can reach 0.05mm or so, the general product precision can be fully satisfied.

The use of silicone moulds for hand board factories can make more than 20 similar products.

The defect of SLA speed prototype is what in reality, the biggest achievement behind the factory is the cost of the machine itself is too high. The cost of the equipment is about 500,000 - 800,000 yuan. If it was a better machine, it would demand millions. This is a very expensive machine in a small area of the craft industry. Bearing in mind that today the cost of CNC is down to a few million dollars, the purchase of SLA is equivalent to the purchase of a dozen or two pieces of CNC equipment. Secondly, the drawback of SLA equipment is the high maintenance cost, repair once, the price of several thousand dollars, if you have to. Signature to change the laser head number of important parts, then the loss is very large, about tens of thousands of dollars of capital. Thus, the equipment used in normal conditions can earn some money. Once it touches the maintenance, the money previously earned will be lost a lot, which is the hand board factory must think about the achievement.

The fixed nature of the hand board factory SLA material invites the high precision and efficiency of the equipment that can only be made from certain specific products. Generally speaking, the material can only choose photosensitive resin, he cannot accept low temperature and high calorie resistance, in addition, photosensitive RE. SN is a toxic substance, harmless to human body and skin, which is also a defect in the SLA processing process.
