Rapid Manufacturing

What is Rapid Manufacturing?

Rapid Manufacturing is a small number of rapid production methods made with real or equivalent materials, where necessary tests and analyzes can be made before the actual mold can be applied and field tests can be applied. It is also a very suitable production choice for the small number of jobs (such as 100 – 1000) in mass production. It is a form of production that uses different production techniques and methods that can be produced without making mold investment. These methods are fast manufacturing techniques such as Silicon Moulding, RIM, Aluminum Moulding.

How to do?

The production technique, which will be monitored, is decided by combining the inspection, data, features and quantity information expected from the rapid production.

PRODUCTION WITH SILICONE MOLDING TECHNIQUE:
Although silicone molding method is also used as a prototype production technique, it is actually a rapid manufacturing technique. The master model required for silicone moulding is produced by a 3D printer or CNC. With silicone mold obtained using the Master model, parts can be produced in a short time.

PRODUCTION WITH RIM (REACTION INJECTION MOLDING) TECHNIQUE:
In production with RIM technique, unlike silicone moulding, polyurethane or aluminum mold is generally preferred. Inside these molds, the 3rd floor, which is a mixture of 2 different materials. a material is injected with low pressure.

With RIM technique, much more products can be obtained from the same mold than silicone mold in production.

PRODUCTION WITH ALUMINUM MOLDING TECHNIQUE:
Aluminium moulding is actually a method of application unlike traditional injection mold production. While injection molds are made of manufacturing steel, the CNC machining times are long, so both time and cost can be produced to high figures. However, since the aluminum material CNC can also be processed much more quickly, the costs are lower.

The number of prints that can be taken in moulds processed with aluminum varies according to the size of the part, the material printed inside and the pressure needed, but varies between 1,000 and 5,000 pieces.

Rapid Manufacturing Applications

Silicone Molding Applications:
Silicone molding method is generally preferred for parts that will be tested.It is more costly to apply the revision needs that may arise in the tests on the mold. Therefore, according to the test results, the parts obtained by silicone moulding become final, then entering mold production is a method of reducing costs and accelerating the process.

The parts obtained by silicone moulding are also frequently used in marketing activities because they are close to high surface quality and visually end-use product. In addition, low-end products that need to be applied to the market urgently or can be produced by silicone moulding method.

The silicone molding method offers a much more economical solution for such productions than conventional methods.

RIM Applications:
RIM is a very intensive method used in rapid manufacturing. It is used more intensively in automotive, white goods and defense industries. It is possible to produce 400-500 units per month.

For example, since the production of commercial vehicles such as buses and tractors is small, the investment in injection molds can be expensive. In these cases, polyurethane structures such as inner dressing parts are usually produced by RIM technique.

Aluminium Mould Applications:
It is an application method that appeals to all sectors that produce plastic parts with traditional injection method. It is possible to shorten the molding processes with this method, which is preferred in terms of introducing the first series to the market faster, pre-series production from real materials and end-use pieces with small numbers. Mold costs are much lower than conventional methods.
