Bronzing silica gel plate, mainly used in plastic toys, craft gifts, hardware electronics, special printing and other industries, it is through the use of silica gel plate as a heat carrier, the exquisite pattern is transferred to the product.The colors are red, orange, brown and so on.

  Application: mainly used for special high temperature resistant products, hot stamping plate, hot stamping silicone roller, heat transfer printing, etc

Product features: high temperature resistance of 350~400℃, hardness requirements can be determined according to the requirements of customer printing patterns. The general hardness is 40A°, 50A°, 60A°, 70A°, 80A°.

  Operation method:

  1. Open an aluminum mold, iron mold or copper mold, which can be closed up and down, like a box. Open a 2 mm wide exhaust groove around the plane of the mold to help discharge the gas in the mold during the process of pressure. 

  2. Clean the mold and brush a layer of demoulding agent inside the mold, (the demoulding agent can be vaseline or detergent) and then dry the following operation. 

  3. Fill the aluminum plate at the bottom of the mold (it is better to make small holes on an aluminum plate above Z, or polish it with roving paper, so as to enhance the adhesion of silica gel and aluminum plate), put the aluminum plate well, and clean the aluminum plate and apply adhesive on it.There can be multiple aluminum plates to fill, and the one that really matters is the one above Z.(The purpose of filling multiple aluminum plates is to adjust a thickness of the pressed silica gel plate and put the two bronzed silica gel and aluminum plate together.) The mold is assumed to be 300 times 300, so that the area of the silica gel plate and aluminum plate is slightly smaller, and the width of the internal width of the mold is left between 2 centimeters so that the excess material and gas can be discharged.This prevents swelling after forming.Note: Brushing the aluminum plate above Z with water from heaven will also help to increase the adhesion between silica gel and aluminum plate. 

  4. Cut the silica gel, the silica gel plate Z is like the aluminum plate around 1 cm smaller, because in the process of pressing, the silica gel will be like the extension around.Then slowly spread the silica gel plate from one end to the aluminum plate, and then roll the stick on the silica gel plate from one end to the other end.The aim is to catch the air.In this way, there will be no air and no bubbles between the pressed silica gel and aluminum plate, and the bonding effect will be better.Take the mold to the press die machine, the mold in the press die at the same time exhaust 2 to 3 times, if the press die machine has a vacuum machine at the same time exhaust 30 seconds of vacuum. 

  5. After 20-30 minutes at pressure of 10 tons and temperature of 160-250, pull out the mold, remove the bronzing plate, and cool naturally.
