Die Used For Precison Slot Coating Field
EXTRUSION DIES
Jwell’s main products are: All kinds of plastic pipe production line (large-diameter PE/PVC double-wall corrugated pipe production line, large-diameter PE/PVC solid wall pipe production line, PP-R/PEX/PE-rt hot and cold water pipe production line, PA/PE/PVC single-wall corrugated pipe production line) , all kinds of plastic profile production line, all kinds of plastic plate, sheet production line, chemical fiber spinning engineering design and manufacture, microcomputer automatic plastic hollow molding machine, plastic auxiliary recycling (crushing, cleaning, granulation) production line, all kinds of single screw/double screw extruder and screw barrel, T mold, net changer, roller, manipulator and other accessories.

Slot coating die can produce very thin and transparent optical coating layer. Meanwhile it can make the coating weight keep the very accurate tolerance range, it is different with the system which the coating fluid wiped on the base materials, our slot coating die is the die which die lip slot is relatively bigger( it can reach 0.0762mm). The coating fluid layer sucted from this die lip can be as thin as 1 μm. 

The slot coating die can control the coating weight tolerance in 5% in the whole width when the coating layer is only 0.002mm or 2 μm. The slot die lip we manufacture is fixed so that it can control the coating layer thickness and width by using the replaceable shims. The coating layer thickness can be from less than 1 μm to 254 μm. This kind of slot die can make different kinds of adhesive (include the special transparent adhesive) battery, ceramic capacitor, decorate surface, Electronic display medium,filtering film, floor board, fuel battery, Magnetic mud,medical product, photoresist, pressure sensitive tape,solar battery,superconductor ,tear tape and film which used in the window.

As China's biggest extrusion equipment manufacturers,we will provide you a whole set standard services with die clean, examination, repair, upgrade, renovate and so on。

Renovates the die each technical specification after JWELL can achieve or very close to the initial standard, we may meet this requirements similarly regarding the non-JWELL production's die.

Every need to repair the die we will strictly according to the following steps:

1、The die remove, cleaning

2、Inspection, evaluation, and communicate with customer requirements for renovation

3、Faded except the original chromium plating

4、Repair damaged surface defects or change the defects in design

5、Replace damaged parts

6、Repairing mold body joints

7、The mold flow channel to polish

8、Reassemble the die

9、Proofreading technical specificationWe provide for you will be a whole set specialized flow type work, the range of service covering general maintenance and completely renovated.
