1. material and cutting
Plexiglass plate conventional size of 1830mm × 1220mm, 2160mm × 1220uum, etc., according to the drawings provided by the customer, in the plate on the cutting line, the size of the cut should be larger than the actual size of the 0.5 ~ 3mm. 5mm or more than 5mm of the plate is directly punched off with a saw, 5mm or less can be used to hook a shallow groove hook knife!
Then use the knife to break the board. When using the chainsaw, should pay attention to safety, two people in step, force to maintain a balanced.
The cutting process is very important, it is related to the following procedures can be carried out smoothly. It must be done: accurate demarcation, set cut reasonable, saw line straight.
Plexiglass advertising sign commonly used machinery and materials see the following table:
Plexiglass processing tools and materials:
Use tools and materials
Cutting electric saws, jigsaws, hook knife, hand curved saws
Planning hand-powered electric planes, tabletop belt sander, abrasive wheels
Brightening treatment polishing cloth wheels, tabletop tape breaker (cloth), flame treatment machine
Brightening treatment polishing cloth wheels, tabletop belt breaker (cloth), flame treatment machine
This process is very important, and it is related to the following processes can be straightened. Flame treatment machine
Bending Line heater (heating tube, heating wire)
Curved surface treatment Large, iron model, press, electric oven
Slotting, drilling Vertical milling machine, table drill (hole drilling bit)
Adhesives Dichloromethane, crystal adhesive, silk-screenable adhesive
Printing Screen printing machine, hand-printing table, high-gloss abrasion-resistant Plexiglass ink
Engraving Engraving machine (plane, three-dimensional), laser engraving machine
2. section planing
Usable planer for uneven organic board section planing straight, there is no electric planer can be used to rough sanding once, and then placed on the belt sander to smooth.
Thin plate with pressure iron fixture will be more than one piece at the same time clamped together, with electric planer or belt sander planing straight. In this way, can improve the work efficiency, and also to ensure the consistency of the size of multiple boards. Professional manufacturers generally have special iron clamps to clamp large organic pieces firmly, and then use the electric planer to push flat. For a small area of the board with a vise to clamp and push flat, the effect is also very good.
3. sanding and polishing
Polishing is the role of the destroyed organic board section to restore its brightness. Already planed sheet, with water sandpaper to further grind fine, and then polished with a polishing machine. From time to time during the polishing process, some polishing soap (green soap, white soap) should be rubbed on the cloth wheel to speed up the polishing process.
Transparent organic boards often have a variety of scratches on the printing or bonding before the polishing process should also be carried out. With the emergence of engraving machines, organic board section also have the use of flame treatment machine for bright treatment, but the effect is not ideal. For high quality requirements of the word plate is best to use a laser cutting machine.
4. Bending
Organic plate processing of various types of display racks often need to bend the plate into various angles.
According to the length of the bending line, you can make a number of different lengths of the heater, the heater with a flat square aluminum alloy profile. Method: First of all, in the aluminum profile on the plane to open a 3 ~ 5mm groove line, so that the heat of the heater tube from the overflow, groove line on both sides with a rigid board attached, can play a role in thermal insulation does not stick to the board.
Then, the quartz heating tube with iron clips fixed in the aluminum tube, connected to the power cord can be used. Organic board bending place, with a hook knife hooked out a shallow line, so that the folded out of the corner line, in order to get both square and round, the size is accurate.
Heating process, the organic plate heating line side must be pressed with a square wood, so that the heating line heat equalization, folded out of the corner of the line will be flat and straight, without the occurrence of a heap of meat or partial fracture phenomenon occurs. Different bending angle, also need to configure different angle of the wooden mold.
5. Slotting and drilling
Signage panels or display racks often have to slot holes, slotting with a vertical milling machine, Ran equipped with a good variety of cutting tools; open holes need to buy a set of combined hole opener, the hole opener can be carded in the desktop drill can be completed on the task of opening holes for holes up to 13mm can be used with an ordinary drill bit.
6. Bonding
The more commonly used adhesive is trichloromethane solution. With a syringe to inhale the solution into the syringe, lighter bonding gap, the bonding effect is very good, for a large area of bonding, you can use crystal adhesive, bonding place of high transparency, but also, the car degree is still good, there is also the use of 502, 110 and other strong adhesives, bonding is also very convenient, but the price is slightly more expensive.
In the advertising industry, both focusing on screen printing and engaged in plexiglass sign engraving and cutting of many enterprises, they also achieved good economic and social benefits.
