How to solve the problem of defective products in making silicone keys

2021-12-20 17:04:52

Causes and Countermeasures of Silicone Keys Bad The color of the silicone key is reversed. 1, put color KEY plate has been reversed color KEY should be checked, correct in time if there is any error. 2. When typing the color KEY, the color KEY shall be checked after the color KEY is reversed, and any errors shall be corrected in time. 3. Drop when coloring KEY, check when teaching complementary color KEY. Glue Overflow of Silicone Keys 1. Improper position of two kinds of raw materials: mutual position of two kinds of raw materials should be adjusted 2, a certain amount of raw material is too heavy: appropriately reduce the weight of this raw material 3. The mold has some miscellaneous materials before discharging. Appropriately reduce the exhaust distance, times and clamping speed (such as low exhaust) to solve, but also can be out of thin material molding. 1. Leakage of conductive particles: check whether the conductive particles are properly placed before discharging. 2. The KEY of the product is relatively high: the conductive size is too small to properly reduce the exhaust distance, exhaust with low pressure and spray less water. 3. The conductive cavity is shallow, and the conductive material is discharged with Teflon auxiliary when the mold is closed. Causes and Countermeasures of Silicone Keys Bad Bean-off of Silicone Keys 1, the mold temperature is not appropriate to adjust (increase) the mold temperature. 2. If the time of adding sulfur is insufficient, the time of adding sulfur shall be appropriately prolonged. 3. If the exhaust is not good, properly adjust the exhaust distance and times, refer to (unfamiliar item 2). 4. Thin conductive particles are used instead of shallow conductive holes. 5. If the conductivity is too long, the appearance has been ground out and changed to the new conductivity. The old conductivity is washed and dried before use. Causes and Countermeasures of Silicone Keys Bad Conductive Overflow of Silicone Keys 1. Use larger conductive particles instead of smaller conductive particles or use Teflon to assist discharging. 2. Repair the conductive hole if the conductive hole does not match with the conductive hole, or if there is a gap. 3. The conductive particles are not hit to the end. 4. Before putting the conductive particles, there is raw rubber in the conductive hole to clean up the mold and then make the conductive particles. 5, conductive particles dirty cleaning conductive particles. Silicone Key Bad Phenomenon Double Beans 1. The conductivity of the upper mold is not taken away by the product. After each product is separated from the mold, check whether the conductivity of the upper mold remains in the conductive cavity before putting the conductivity, and pick up the residual conductivity. 2. When absorbing the conductive particles, they have already overlapped. After absorbing the conductive particles, check whether there is overlapping phenomenon and remove the conduction. 3. Check before replaying the conductive production, and the stamper will take the conductive away. 4, lack of material, immature in the lack of material and immature place, should pay attention to the existence of conductive holes. 5, conductive particles wet conductive baking after use. Cracking of Silicone Key Deficiency 1, the mold temperature is too high to reduce the mold temperature. 2, the product is not enough to add sulfur, appropriate to increase the sulfur time. 3. Rough sand blasting and electroplating on the surface of the mold. 4. When the product is separated from the mold, the upper and lower molds are not good. Only one side of the mold is sprayed with demoulding water to make the product all attached to one side of the mold. Or add KP-10 to the material. 5. When the product is torn off manually, use an air gun to blow air to assist the product to leave the mold. www.mingzhen2006.com
