The job lot production is demanded in industry, machinery manufacturing and in any production, in car service centers, souvenir shops, almost in any scope of activity.
We often face the situation of an enterprise having expensive imported equipment. The spare parts for it are impossible to find or cost a lot. Either way, it’s easier to order a prototype made of plastic and substitute an original part with it.
Apart from this, there is a chance of keeping original parts through replacing them by plastic prototypes.
Plastic has unique physical and chemical properties. For example, the correlation of density and solidity in plastic products is the highest if compared with other industrial materials. Due to low density, the plastic is used in machinery-, aircraft- and ship-engineering. Owing to its high dielectric properties, it is also applied in the production of electronics and radio technique.
The characteristics of polymers are easy to “correct”. If introducing certain components into primary formula when manufacturing plastic products, it will be possible to change thermal and electric conductivity, density, solidity and other features. The plastic is widely used in different domains of industry, as every manufacturer can achieve a desired result via proper manipulations.
As a rule, thermoplastics are used for printing, but there are exceptions, namely the composite materials that contain different additions. Still, they are based on thermoplastics anyway. The most popular kinds are:
- 1. Polylactide (PLA)
- 2. Acrylonitrile-butadiene-styrene (ABS)
- 3. Polyvinyl alcohol (PVA)
- 4. Nylon (Nylon)
- 5. Polycarbonate (PC)
- 6. High Density Polyethylene (HDPE)
- 7. Polypropylene (PP)
- 8. Polycaprolactone (PLC)
- 9. Polyphenylsulphone (PPSU)
- 10. Poly Methyl Methacrylate (Acrylic, Organic Glass, Acryl, PMMA)
- 11. Polyethylene Terephtalate (PET)
- 12. High-impact polystyrene (HIPS)
- 13. Wood imitators (LAYWOO-D3, BambooFill)
- 14. Sandstone imitators (Laybrick)
- 15. Metal imitators (BronzeFill)
Simple or unreinforced ones consists of polymers exceptionally. There may be added the following components into the composition of complex or reinforced ones:
- Stabilizers (delay aging of material);
- Catalysts (accelerate hardening of mass);
- Lubricating substances (prevent plastic from getting stuck to press-form);
- Fillers (improve physical and chemical features of material and make it cheaper herewith);
- Coloring materials (paint plastic in necessary color).
Small manufacturing. To produce a limited number of products, the 3D printing is most often used. This method is notable for low price and simplicity. There is an impossibility of manufacturing a large-sized production and also relatively low rate of printing among its drawbacks. Hence, the technology is applied for production of exclusive elements of interior, accessories, decorations, etc.
Job lot production (50-200 pieces). An optimal method of production is casting into press-form from silicone. It is ideal for manufacturing small production parties with simple configuration, like furniture fittings, buttons, plastic details on a by-order basis for automobile and medical industry.
Mass production (starting from 200 pieces and higher). In case of mass production, high-pressure casting is used. The technology comes to injecting polymer into press-form and then cooling it. This method of production is rather expensive. On this account, this method is used for mass production of plastic goods on a by-order basis. The goods include litters for food industry, dishes, toys, stationery, etc.
The ultimate price depends on a number of characteristics:
- Specified deadlines;
- Print run;
- Method of production;
- Availability of ready-made press-forms;
- The kind of plastic used for production.
Besides that, the presence of sources, like 3D models, drawings, original sample, etc influence the price, too.
