Changshu smoothly da plastic products factory summary plastic extruder so unhappy four big reasons

Compared to domestic plastic extruder expensive imported plastic extruding machine more approachable, but customers also reaction of domestic plastic extruder drive fast.
Well da plastic products factory in changshu combined with their own situation, the summary of plastic extruder great mainly in four aspects: extrusion die die, cold roll, corona, online synchronous.
the first point, the die head
not imported extrusion die die must be better than domestic, because import is very tall to the requirement of the die, the design flow, according to the liquidity of the designer. Import die adopts the high quality materials, the production of the product quality is also very good. Using imported die head does not represent can produce high quality membrane, commodity products, need the whole line. Now, with the improvement of industries, domestic die processing equipment in many other aspects of material, heat treatment, electroplating has made great progress. Nearly ten years, the domestic equipment basic domestic extrusion die head. In recent years, some products began to import die configuration, but still is given priority to with domestic die head.
the second point, cold roll
a lot of people think MTK unhappiness is die and mechanical design has a problem, actually roll also is a key problem, the domestic stretch film roll in 18 mm thick, abroad in 8 mm thick, stretch film suddenly cold, too thick will leave unpleasant, finalize the design is too slow JinKouJi thin so quickly.
the third point, corona
the electric airsick didn't put the film flattening when into the corona, makes the corona uneven, must put the film flattening before into the corona, corona roll liquid silicone hardness in 70 degrees, the best companies in domestic are now about 65 degree, hardness is not enough.
the fourth, online synchronous
the domestic many flow unit synchronization is around 5%, boot slowly speed, uniform thickness, but the waste is very big, the main problem is the electrical design and selection of reducer.
