wood grain machine Wooden Transfer-Printing of Aluminium Profile Equipment General Introduction: This equipment create vacuum transfer effect with covering type and suction type. It can engender the effect of vivid wooden grain and the feeling of marble which make the wooden grain seems more natural with clear grains and strong third dimension feeling. It mainly serve the turn of the heat transfer-printing such as high-temperature enduring plastic material or the metal surface after spraying, broiling or electrophoresis. Furthermore, after-treatment production has high quality for sun-proof, wear-resistant and anti corrosion. It would keep the color without any change for ten years at least even in the open air. This machine could be simply operated and improve the producing benefit largely with double side working table which could work separately. This machine is widely used for the surface heat-transferring decoration such as top-grade aluminum alloy window, metal decoration sheet, theft-proof door, metal moulding door, metal ceiling, curtain rail and other Aluminium material. ,The general operation procedure of the craft 1)Film-covered mode Preparation before the producing-----Material quality checking------- furnace heating------paper laying-------loading-----paper spreading-------cover closing -----vacuum application-----product inspection -------transfer printing in the furnace------unloading----------back-check----------packing 2)Bags-application mode preparation before the producing-----Material quality checking------- furnace heating------bags cutting-----loading-----paper spreading-----cover closing-----vacuum rifle stand-----vacuum application-----product inspection----- transfer-printing in the furnace-----unloading-----inspecting-----packing Technical operate rule: 1, Preparation before the producing (1)Checking whether the water tank to be set over 1/2 location, and to be operated properly for the power supply, pressure , compressed air pressure and the blower, also need to check the furnace-Tem. It is necessary to make sure all the equipment can work properly before arranging the production. (2) Prepare the wooden paper according with “product plan” (3) No dust in the transfer-printing furnace and work place etc. 2. Quality inspection (before loading) (1)Checking the surface quality and shape of produced profile according to {Inner Quality Standard}.Put the surface defective profile on to specify area for further inspection such as curling, wresting, Bubbling and bumps. (2)Checking if there is defective affect the quality of wooden transfer-printing such as oil, blot, serious scratch and color deviation etc. It is necessary to treat them as unqualified products. (We can clean the oil by rag). Process audit inspect the quality above 5 Nos. 3 Inner furnace heating The temperature for empty furnace heating is 180-190°C,make sure the constant Tem. Of furnace body for fast heating over 1.2 hours.In order to reduce the differece of furnace body heat,we need to warm up it together with operate desk for 10 mins before loading. 4. Paper spreading Film-covering mode: (1)Spreading the heat-resistant strap on two ends according to the length of profile before spreading the paper. Do not press the profile part excess 2cm, and prevent the strap be scratch. (2)Upward spreading wooden transfer face of the paper at the underside of operate desk, the wooden paper must be longer than workpiece, and using the feather duster to flattening the wooden paper. Bags-application mode (1)Cutting the paper bag according to the profile size, and put the profile into the bag. Commonly, cap bag is bigger more than vacuum application for 1/3 before vacuum. (2) Put the profile into the PET bag and do up the envelop. 5. Loading (1)Operator must make sure cleaning hands or wear the cleaning glove; the profiles being processed must be qualified through test. (2)Adopting the flat type for loading the profiles, the distance between the profiles would be decided by the dimension of the profiles. Overlap is not allowed and the should make sure the suitable distance in order to make wood grain on the profiles completely. 6. Covering Open the pressure switch, lock it and make it closing for upper and down side. 7. Vacuum Vacuum time we need gradually open the switch and make sure the pressure value between 0.001-0.002 MPa and meantime deal the furrow and applying the concaving place using hands, make sure the wood grain paper sticking one the profile tightly and then make raise the pressure to 0.05-0.07Mpa 8. Transferring Open the oven, make the working table with profiles into the oven, then setting the temperature between 175 185°C, and keep 6-8 minutes( time and temp setting should according to the detail technical requirement. 9. Profile unloading Turn off the vacuum switch one minute prior the dealing, the equipment would come out automatically, open the pressure switch and take out the profiles 10. Removing the paper Removing the paper from the profiles and make it cooling down quickly, inspecting the quality of the wood grain transfer quality. 11. First inspection Before the batch production, we need check the transferred material before the batch production, we need to check the transferred material strictly comparing to the color ban, and then we can make batch production after confirming inerrability, but inspect in the mid way at any time is also necessary. 12. Final inspection For quality product after inspection, packing them according to order requirment, it is necessary to handle with care during operation; we can not scratch the profile. IV.
