Table of Contents

Customization is being hailed as one of the fastest-growing trends in manufacturing. In this day and age, skilled labour is expensive and difficult to find. As many industries progress, there is a shift to move toward more automated processes for producing goods and as a result, old-school manual work practices are being reduced. This is where customized manufacturing using CNC processes opens up new doors for creative possibilities, resource optimization, and the time and energy savings that it brings. The machining process may differ at different shops, but they usually follow the same principle for production.

There are several industries that utilize CNC-machined molds to produce their products, and the options to produce anything with molds are endless! Creating movie props, building toys, furniture, automotive equipment, construction, and architectural elements, and even replicating duplicates of family heirlooms can all be made possible by means of using molds for manufacturing. If there is any idea you have in mind, it can be custom cast in foam with the appropriate processes, tools, and materials. Read ahead to learn all about the use of foam molds to create innovative products and open up new markets with the help of FROG3D’s foam carving system.


The Use Of Molds In Customized Manufacturing

Different manufacturing processes demand the shaping of raw materials with a fixed tool, structure, or frame which is known as the ‘mold’. Molds are essential to manufacturing processes and their central purpose is to reproduce consistent replicas of the given design, and some form materials that are used in mold-making can include the following:

  • Plastics
  • Ceramics
  • Wood
  • Foam

Foam is a lightweight and durable material that can be processed into various shapes, and can be utilized in a variety of everyday products. It is a cost-effective material and is also easily available in all shapes, sizes, and forms. Foam is used across a range of industries thanks to its versatility, practicality, and durability. This material is used in amazing and never-seen-before creations and expands the possibility for even more elaborate product designs and ideas. Due to this, standard formwork has been decreasing in popularity because it is not flexible enough to support more sophisticated and complex curvatures.

Foam molding grants several industries endless possibilities with regard to product design and developing new product lines. When utilizing foam-molding processes, it is possible to fabricate custom-shaped parts and easily merge smaller parts into a larger, finished design to assemble and deliver end products. This allows the possibility to produce the smallest products to even larger-than-life creations. Foam is also more malleable to work with when creating precast shapes, and it can be machined or carved into solid structural forms instead of expending extra time and energy that goes into laminating and forming wood.


Using Foam To Create Molds And Precast Products

Since material processing techniques and technologies have been advancing rapidly, it allows for concrete and cement to be used in creative and innovative ways that were seldom seen before, which introduces new ideas for more elaborate designs and structures. As mentioned previously, standard formwork has decreased as it is just not flexible enough to support these complicated curvatures. For precast shapes, foam is a much more reasonable material to work with since it can be carved or machined into solid structural forms instead of the laboursome and time-consuming process of laminating and forming wood, with the added work of building the supporting structures to hold them in place.

Without molds, concrete would be shapeless. It is useful to note that concrete has been making a significant impact on design ideas for many industries, and notably within the construction industry for the manufacturing of manholes, catch basins, and pipes. The businesses that pour concrete mixes into molds require a material that can be precisely shaped, and this is where foam plays a crucial part. Well-made molds are crucial in boosting efficiency and optimizing material use, and foam is a versatile and commonly used material for precast mold production as it is fairly dense and can be cut, sanded, routed, and shaped easily. When creating precast molds, EPS foam is a superior material as it is simple to shape and finish the mold and custom-made molds can be easily facilitated by Streamline Automation’s FROG3D® CNC machines such as the FROGWire™ and FROGMill™.
