Characteristic Explanation ：
              ． By turning the spiral screw to adjust the abrasion between mold and plunger  
                   - turning about 1/4 of a circle can close a mold service life of about 50,000 times. 
              ． Installation and detachment are easy, simple, high performance, and low price. 
              ． The plunger can be used in the following equipments: small orifice template, 
                    intermediate template, die of small orifice of two-stage top effluence, or sliding 
                    base. 
              ．  4 pieces of 12φ required for the weight of mold below 100kg
                    4 pieces of 20φ required for the weight of mold below 1000kg 
                    6 pieces of 20φ required for the weight of mold upward 1000kg 
              ．  Resin part of the plunger is embedded about 3cm into a male template 
              ．  The diameter of orifice of a hemale template is processed within, the range
                    +0.1mm by a H7 hinging knife. 
              ．  The internal surface of a female template is processed to ▽▽▽- ▽▽▽▽ 
                    and the outer surface is processed into R type. If reverse angle is made in the C
                    face, there will be poorer service life. 
              ．  Don’t add grease onto the resin part, because it reduces the abrasion and lessen 
                    its function.
