Another purpose of pad printing silicone is to make the glue into a pad printing head. The purpose of the pad printing head is to use a printing method, mainly because the ink is used to print text on the surface of the silicone product through the pad printing head. , graphics and images are now becoming an important specialty printing. For example, the text and pattern on the silicone button on the surface of the mobile phone is printed by this type of printing, and the surface of the silicone rubber products of many electronic products such as a computer silicone keyboard is printed by pad printing. The process of printing silicone is relatively simple. The steel (or copper, thermoplastic plastic) gravure is used, and the surface of the gravure ink is applied to the surface of the printing head by using a curved printing head made of silicone rubber material. The surface of the object can be printed to print characters, patterns, and the like. The pad printing silicone button has excellent durability, no deformation, no oil and good ink transfer.
There are 2 kinds of pad printing gels, one is 10:1, the one is 100:2, and the 10:1 is additive-printed silica gel. It can pass the food grade environmentally-certified liquid glue, non-toxic and tasteless. , the color can be adjusted according to customer requirements! This kind of 100:2 is a condensation type pad printing silica gel, and it belongs to industrial grade silica gel. It is not environmentally friendly!

Although there are many types of tapping screws, they all have the following similarities:
(1) are generally made of carbonized carbon steel (accounting for 99% of total production). It can also be made of stainless steel or non-ferrous metals.
(2) The product must be heat treated. Carbon steel tapping screws must be carbonized and stainless steel tapping screws must be solution hardened. In order to make tapping screws to meet the requirements of the standard of mechanical properties and performance.
(3) The product surface hardness is high, the core toughness is good. That is, "soft inside strong outside". This is a major feature of tapping Screw performance requirements. If the surface hardness is low, it can not be screwed into the matrix; If the core toughness is poor, a twist will break, can not be used. So "inside soft outside steel" is self-tapping screw to meet the use of performance, very important requirements.
(4) The surface of the product needs surface protection treatment, generally electroplating treatment. Some product surface must be treated by phosphate (photostatting), such as wall panel self - tapping screws for photostatting.
(5) Production by cold heading process. It is recommended to use high-speed cold heading machine and high-speed wire rolling machine or high-speed planetary wire rolling machine. High speed is emphasized here to ensure product quality. Only the head of tapping screw produced by high-speed machine is well formed and the thread quality is high.
