1.   Precision choice.

With the fierce market competition increasing, an enterprise want the continued development and to improve their competitive ability, we should not only save cost, but also improve the product quality.Maybe generally puncher can produce a qualified products, but if want all products are good, you need to choose and buy the high precision press machine that can be guaranteed. Puncher precision mainly displaying as follows: 1. degree of parallelism; 2. verticality;3. total backlash. To ensure that all dead spots in the dynamic within the error, make each production qualified,and the parts in the mould not damaged. SAMDUN puncher accuracy and precision up to the JIS standard, special processing technology makes the crankshaft keep roundness, so the parallel degree of the top and bottom dead centre are extremely accurate. High precision press machine can not only produced good products, but also less damage to molds, not only save the mold maintenance time,but also save maintenance cost.

2.   Speed choice

Now on the market domestic puncher and Taiwan puncher have two kinds of speed called high speed, one high speed for the 400 times/minute, another for 1000 times/minutes. If your mould demand the speed for 300 times every minute or higher, you should choose the 1000 times / minute one. Because the equipment can't limit use, and the speed within 400 times/minute usually have no forceful lubrication system,the joints part only use butter lubrication. And the puncher pin structure adopt sliding pieces type, so the accuracy is hard to ensure, long time working will wear soon,and then precision drop, mould damaged, machine and tooling maintenance rate becomes high, and delay time,also can influence delivery date. Such as SHENZHEN LIHAO SAMDUN PUNCHER the speed can up to 1000 times/minute, can well meet the requirements of your speed. And the use of three round guide pin type punch system, precision and excellent thermal stability, mandatory under lubricating oil almost no wear.

3、External view

The fine structure can guarantee the accuracy of the equipment. SAMDUN punch appearance structure has be imitated in the industry. The feet of a punch is based,and the body is the guarantee of the fuselage precision.The SAMDUN puncher the crankshaft and connected all use Japanese import steel. Bearing adopt the Sweden SKF bearing system, in order to make the stamping work (dynamic) with higher precision.And the puncher also adopt the Frequency conversion motor ,low power consumption,under the same tonnage can save 30% energy when working.

4、After-sale service

The after-sales service is also the considered key when choose and buy equipment, equipment need use for a long time,some trouble will not avoid. After-sales service should consider three questions: first, punch factory’s response and maintenance speed. Second, maintenance costs. Third, the difficulty of the maintenance for the purchaser itself. SHENZHEN  LIHAO  SAMDUN respond quickly and the fix time is short, with professional maintenance team. And SAMDUN punch using NC control, it’s simple and easy for yourself to maintenance, only need to change such as keys accessories, very low cost.
