CNC machines enable thermoforming technology to produce high-quality plastic parts with lightning-fast turnaround. Their team can process hard polymers as well as other materials including wood, composites, and aluminium thanks to a powerful oscillating knife system, which is the essential mechanism.
The CNC machine can also cut through EPS, corrugated cardboard, rubber, cork, felt, wood, and leather in addition to X-Board, graphic foam board, and other types of foam board used as gaskets.
The Global CNC thermoforming machine market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
In the product development process, machining prototype moulds is the initial use for their 5-Axis CNC machines. Thermoformers can be divided into two groups: thin gauge and thick gauge. Thick gauge thermoforming is done by Reliable Formed Plastics.
For the manufacture of the initial moulds, they commonly use MDF (medium-density fiberboard). MDF is a less expensive option to the more expensive epoxy board, despite the fact that it is only effective for a relatively short run in vacuum thermoforming because it can deteriorate over longer runs.
As a result, by using MDF at the mould prototype stage, they may make changes to the mould and reduce the cost to the client before utilising the more expensive production run tooling.
For forming plastics, there are numerous methods that can be used. Blow moulding, rotational moulding, injection moulding, and thermoforming are a few of them. Due to the affordable price of moulds and tools, thermoforming is frequently the preferred method, particularly for big parts and prototyping.
When thermoforming, a plastic sheet is heated to a temperature that makes it malleable, stretched over the surface of a mould, and the air between the plastic and the mould is removed using a vacuum.
By doing this, a plastic shell is produced whose surface corresponds to the mould’s shape. After being cooled to a solid state, the formed sheet is cut into a useful plastic product. With a 2′–3′ draw, Reliable Formed Plastics can form sheets up to 6’x12′ in size.
