Common burr treatment method

Common burr treatment method for silicone rubber products 1.Deburring by hand Manual trimming is a traditional trimming method，It debur by punch die cutting and scissors and a scraper.Manual operation may lead to differences in product quality and speed, so it is necessary to make clear the product parts and technical requirements before deburring, they should master the correct deburring methods and konw how to use the tools correctly.

O-ring's hardness measurement method

O-ring's hardness measurement method is as follows: Measuring instrument Measurement by micro hardness tester to complete, hardness tester should conform to GB/T6032-1985 "vulcanized rubber hardness determination (30-85IRHI) micro test method" test specimen 1.The inner diameter of the standard sample is 14mm±0.17mm.The cross section diameter is 2.65mm±0.09mm, need 3 pieces? 2.For O-rings with a cross section diameter of more than 6mm or an inner diameter of more than 30mm, their segments can be cut and measured, and the results cannot be compared with the standard test results 3.Test procedures Follow the test procedure of GB/T 6032 4.Test result representation:The measured results are 3. Take the middle digit and the whole digit ?

How to measure the size of O-ring

The following two methods are generally used to measure the size of O-ring 1.Projector measurement In short, measure the shadow of the O-ring. We usually choose projector as the measuring tool.In general, O-rings are measured to measure the size of the outside diameter and inside diameter. When do the measurement ,The diameter is measured at the top, bottom, left, and right four points of the O-ring. The following methods are applicable to both the outside and inside diameters of the O-ring 1)In the projector, according to the size of the product to adjust the multiple size of the lens, the lens will be adjusted clearly 2)Place the coordinates on one edge of the O-ring, close to the projector coordinate lines 3)Find the icon marked with a circle on the projector, click the icon, and then press the OK button 4）Move the coordinates to the second point of the o-ring and close the coordinate line to the edge of the O-ring,then press the OK button; And so on, so that after four points of the O-ring, the diameter is measured 2.Optical image measuring instrument,that is to measure the O-ring itself. The method is basically the same as the projector ?

Silicone rubber mold maintenance

Silicone rubber mould maintenance is very improtant for its good work, to ensure that the quality of the stamping parts qualified, to avoid the occurrence of accidents, to extend its service life, to ensure the normal production. The main forms of mold's failure 1.abrasion 2.breakag(Include cracking, chipping, chipping, falling pieces and peeling) 3.plastic deformation? In order to ensure the quality of stamping parts and prolong the service life of the die, it is necessary to clean and clean the mold 1)Daily cleaning Dust cleaning of mold surface:After wiping with a clean cloth, touch the surface of the mold with your hand, until you can't feel the dust 2)Mold guide sleeve, guide pillar cleaning:Use a rag to wipe the oil block of the guide sleeve, guide pillar and guide block, and then wipe with a small amount of oil to lubricate 3)Clean the punching area:Use a hammer to remove all the waste materials in the hole and the waste materials stuck on the slide plate and the scrap materials at the cutting edge 4)For moulds with coatings, the stretched surface of the moulds must be cleaned, and the surface must be confirmed by hand. The first piece of material in production must be wiped clean with a rag. After production, the moulds must be coated with a little oil Clean up regularly 1)The surface of the mould must be cleaned after the mould is repaired 2)In the regular maintenance process, the outer surface of the mold, disassembly, replacement parts are thoroughly cleaned 3)Every once in a while, the mold must be completely dismantled, and then all the goods must be cleaned
