Pad printing means transferred the pattern to the toy steel products through the silicon pad.
Silicone printing quality requirements fine, no impurities, good resilience, oil well, a clear pattern printing.
Application:
Mainly for the printing of plastic toys, electroplating products, electronic toys, trademarks and irregular pattern. Pad printing is done on the pattern plate carrier through the rubber head, then the pattern is transferred to the toy steel products.
Pad Silicone Product Instructions:
First, put a clean mold cleaning with detergent, then dry the mold in water or with an air gun to dry, and apply a release agent.
Second, silicone pad, the normal ratio of silicone oil, based on customer requirements and given, if a customer requires a large area of the printed pattern, required soft head, the more increase in silicone oil. Instead, you need to glue head hardness of not less silicone oil added, the hardness general printing of plastic to 15A ~ 25A ° is suitable, if the silicone oil added is too large, too soft plastic head, showed a limited number of print even the best silicone quality will be undermined its molecular weight silicone oil, and produce no wear, no solvent and aging.
Third, introduce the normal ratio is as follows: 100 g of silica gel was added 30 grams of silicone oil, plastic head hardness 15A °, adapt printing pattern alloy car Aberdeen and small contact area is relatively small products. As required pressure contact surface or need soft head, the proportion of silica and silicone oil can be 100: 30,100: 50 range, but note that the larger the amount of silicone oil added, the softer the rubber head, the number of printing of , abrasion resistance and solvent resistance will reduce and reduce, the number of printing products will be reduced, resulting in increased costs, wasted materials.
Fourth, a chemical reaction and the addition amount of the curing agent of colloidal silica proportion as follows: Take 100 g of silica gel, 50 g of silicone oil, followed by mixing with stirring until the silicone oil with the silica stir evenly, then 2% of the total weight of silica and silicone - 3% hardener is added, and then stirred for 2-3 minutes, it can be evacuated. Evacuation time is generally no more than 10 minutes, taking too long, colloidal quickly cured, it will affect the quality of inverted plastic.
Pad Silicone Product Features:
With good elasticity, deformation, high temperature, and low shrinkage, mainly for the hand model design and development of small quantities of copy products.

How to Make Pad Printing Pads
1: First clean the tools such as: molds (copper molds, crystal molds, blister covers, etc.), mixing buckets, and mixing sticks with detergent (detergent, Basu copper wiping water, etc.) Use different cleaning agents, do not use extremely corrosive solvents, such as thinner, net washing water, etc.). Then wipe it clean completely without any foreign matter and stains. Then apply a layer of release agent on the mold: such as Vaseline, detergent, etc. (some types of mold do not need to be coated with release agent).
2: Calculate the glue and silicone oil according to the volume of the mold (adding silicone oil can properly adjust the hardness of the glue head. If the amount is too much, the wear resistance of the glue head will be poor.), mix and stir evenly. Then let sit for 10 minutes or vacuum up.
3: Add a certain weight (ratio) of 2-3% curing agent according to the total weight of the glue and silicone oil, and stir again quickly and evenly for 3-5 minutes. Afterwards, vacuum defoaming is carried out immediately if conditions permit, which is called forced defoaming method; vacuum defoaming without vacuum defoaming is called waiting for natural defoaming method. (Note: . The amount of curing agent should be tested according to the data provided by the supplier to find the amount suitable for your own operation method; . The specific method to choose for defoaming depends on the curing speed.)
4: Put the mixture after vacuum defoaming or static defoaming. Slowly pour into the mold from the edge of the mold. Do not pour a large amount into the center of the mold, as this will increase the amount of air bubbles and reduce the service life of the rubber head.
5: After the vacuumed mixture is poured into the mold, it can be covered with wood chips; the naturally defoamed mixture is poured into the mold and left to stand for about 30 minutes before being covered with wood chips.
6: The rubber head after demoulding is placed for 3 days, the use effect is better; if possible, put it in the refrigerator for better use effect.
