CNC machines
Till Aug 2020, JW Mold has 4 sets CNC machines in house, 2 of them are a high-speed machine with 24000 RPM, machining tolerance +/- 0.01mm, Cut area 600*500*300 and 710*460*570 mm respectively the biggest one is ”Hartford 1270” with1270x650*630mm cut stroke. Machining tolerance within 0.025mm. Another big CNC machine with cut area 1000*600*600mm, tolerance +/- 0.015mm
More CNC machines will be equipped in the year 2021. planning add one more big size CNC machining center with stroke 1500*1000 mm
EDM machines
Currently, there are 4 sets EDM machines inhouse, one of them is a high precision CNC machine from Swiss company” Charmilles” with machining tolerance 0.005 mm, can process Mirror level finish and VDI 3400 series finish the bigger ones have 800mmx600*500mm stroke and tolerance within 0.025mm.
More EDM machines will be equipped in the year 2021. planning buy one big size double head CNC machine with stroke 1300*800*600mm for Process the “Auto Grille “ molds and “washing machine tub” molds
1.All operations according to standard operating instructions.
2. Full dimensions measure on electrodes before Process EDM.
Wire cut and gun drilling machines
Above is the Japan Sodick precision EDW machine with tolerance +/- 0.005mm. Another 2 sets precision EDW machines are from Taiwan with tolerance +/- 0.01mm
The Deep hole drillings are outsourced From a gun drill shop nearby, within 300 meters or 0.3KM from our tool shop. That shop has 4 sets of big machines with Max drill depth 1.6m per side. So from both sides can drill the 3-meter long steel plate. The holes diameter can be range 3mm to 80mm
In total 5 sets cranes in the JW tool shop.
2 sets 1T, 2 sets with 3T, and 1 set can lift 7.5T(7500KGS). that means 80% of big automotive or appliances tools can build in our here.
The Meeting room
Has high definition projector and phone devices
Can call to Foreign clients to discuss project details
The Differences with other tool shops:
1) Owner directly managed So could provide most aggressive but achievable prices and lead time
2) Separate mold building by several teams for the best management of cost/lead time.
3) Finish all molding surface through machining, hand grinding is not permitted except those prototype tools.
4) The employee turnover as low as 5-10% each year .this is very important for experience accumulation and keep quality stable
Tool testing and Molding production
JW Molding shop is 600 meters far from JW tool shop, has 100-250T machines in the house for both tool testing and production purposes
Whatever test inside or outside of JW, JW will Follow customers, stood trial procedures, and standards. Use scientific mold trial method, check feed balancing by 50%, and 80% percent with consecutive 5 shots put printed cooling diagram and temp. sensors beside the machine, connect cooling lines separately without mix up.
Send info to the customer just after the trial finish. Record the issues and solve them one by one after the tool of the machine.
For big tool trials, we do it outside in a professional tool test company which is 1200 meters far from the JW tool shop. They have 15 sets standard machines range 80-1000T, 1 set 250T two-color machine, with core side rotatable and 2 parallel inject units.
Also, bigger machines for example 1300-2000T are available in another professional tool test company with 20 KM distance.
Some parts has heavy thickness or much glass fiber-filled will require big machines for easier get full shot.
