Carlsson & Möller has increased its exposure within medical technology and, to meet market demand, a modern cleanroom of ISO Class 8 GMP Class D has been invested in.
The cleanroom is built to handle packing, packaging, washing, and drying. We also undertake the assembly of our machined parts in construction plastics with parts made of, for example, metal.
Thermoplastics (amorphous and semi-crystalline) are most common for cutting operations (CNC plastic machining). The plastics have different properties, which is why it is important to have the right tools and settings. Speed, feed rate, and clearance angle are some factors that are important for good machining with minimal scrap.
It is important during machining that the plastic blank is securely fastened. Incorrect clamping of the plastic blank leads to vibrations, which cause poor Ra values and dimensions outside of tolerance.
Cutting values and the right tools are also very important for achieving a good surface finish. Cutting speed, feed, and clearance angle are things that affect the final result.
There are several different manufacturing processes for producing drawn plastic articles. The most common are CNC machining, vacuum forming, rotational moulding, casting, 3D printing, injection moulding, and extrusion.
Of these methods, CNC machining is the most expensive because it starts with a semi-finished blank, which results in scrap during machining and an extra production step to produce a semi-finished product that can be flat, pipe or rod. CNC machining is well suited for very tight tolerances, advanced geometry, low quantities, or if the part requires continuous revision changes.
In CNC machining, you start with an empty machine without fixtures. During setup costs, the machine is prepared for the current machining process. This can involve loading the machine with the correct tools, mounting vices or vacuum tables in the machine, downloading CAM programs, etc. In other words, everything required to machine the parts.
Unit cost is the actual cost of manufacturing time in the machine.
Every CNC machining process therefore includes both a setup cost and a unit cost. In addition to this, other costs may be incurred, such as tooling costs.
