You can come to us for processing of plastic materials. We apply processing techniques for plastics and always seek to achieve products with the highest possible quality. With our extensive machine park there are many options available. We can drill, bend, trim, cold form, punch, glue, polish, tap, saw and laminate.
Techniques for processing plastics
Below you will find the various processing techniques that we apply described in more detail. In doing so we seek to indicate the tolerances as accurately as possible and to take account of the thermal expansion coefficient.
With so-called heating tables, small parts of for example acrylic are heated up. This makes the material plastic and it can be bent. The maximum breadth is 2.300mm. On the accompanying bending table the material can be bent to the correct angle and fixed, so that following cooling the material stays in the right shape. Multiple bends can be made in one operation.
Using a radial drill it is possible amongst other things to drill and to tap.
A CNC router is used for trimming plastic. It is a machine with a so-called flat table provided with a strong vacuum. The table can be divided, for example into working halves. A plate is laid on one side while it is being trimmed on the other side. With the software available it is possible to cut various measurements and shapes in an optimal manner from one large plate (nesting module). Tolerances are plus or minus 0.1 mm in length and breadth. The small lower and upper cutters are used for small trimming work, cutting edges, rounding corners, etc.
Cold forming plastic
This is applied for polycarbonate. The manufacture for example of machine covers can be realised this way. De maximum size is 2.500mm and the maximum pressure is 83 ton. In fact this machine bends the material cold and sets it at the desired angle.
Glueing or bonding plastic materials is one of our core activities. For this you can use contact, 1K or 2K glues. Glueing plastic units/parts amounting to more than 60,000 units a year per customer is just right for Allplast. Two ovens are available to support glueing activities. A conveyor belt oven at 35°C and a vacuum oven up to 90°C.
Polishing/flame polishing of plastic
Here roughness on sawn or trimmed sides is melted away. In this way the surface becomes nice and shiny and clear. It is the only way to polish round surfaces and interior contours.
Diamond polishing of plastic
Here a layer of 0.5mm is removed with a diamond cutter, creating a nice clear and attractively polished surface. Material up to a maximum of approximately 20mm can be polished. This technique is only applicable for material with flat sides. The accompanying framework and the so-called run-through system offer the possibility of polishing the sides of very long plates.
Plastic is sawn using a panel saw: size 4,200 x 4,200mm. Maximum sawing thickness is 90mm. The saw is provided with rollers so that the plates do not get scratched. The saw is also provided with a suction fan to prevent the plates becoming dusty. Tolerances: -/- and + 0.2mm
Shape cutting saw for plastic
This is our smaller saw, with which small production runs are accurately sawn. Possibilities also include cutting at an angle and customised cutting of an individual plate. Tolerances: dependent for each assignment on the material and other circumstances, such as the person who saws the material.
Allplast develops and produces antiballistic glazing/laminates from PC/PMMA (and glass). These products are used as (personal) safety materials. Examples include bullet-proof visors and shields or impact resistant safety glass. Allplast has two autoclaves in use for this line of production (4,500m3 and 22,000m3 volume). We produce for both the private sector and for government (defence).
Curious about the possibilities?
In processing plastic plate the possibilities relating to shapes, processing and assembly are virtually endless. A solution can be sought together with our product developers, if there is no immediately obvious solution. Allplast is always willing to talk about the possibility of tailored development projects and small production runs. Feel free to contact us to talk about the possibilities.
