Thermoforming involves creating a mold of your product over which a thin sheet of plastic is heated and formed using vacuum, pressure or mechanical force. The plastic sheet takes the shape of the mold and extra material is then trimmed off.

A 'master pattern' of the product is created using CNC Machining or high-resolution 3D Printing with the required surface finish. This pattern is then used to create a urethane or silicone mold into which a suitable resin can be poured in order to create multiple copies of the product. The mold typically lasts for around 20 runs.

3D Printed molds can prove to be a low cost way for testing production-grade materials and processes at low quantities but it is currently limited to small parts and yet to be adopted by the industry at large.

Since this process involves very low pressure and temperatures, the mold can be made from inexpensive materials like plastic or wood. Surface finish is important as the formed product picks up small details on the mold.

Thermoforming, however, cannot be used to produce highly complex parts which the other processes can. It is therefore limited to 'relatively' simple products like packaging trays, large panels of appliances, vehicle door panels, dashboards, simple product housings etc.

A startup developing a new product from scratch faces high uncertainty of whether their product will be successful in the market or not. Therefore, it is hard for them to invest several thousand dollars for injection molding of an unproven product idea.

CNC machining is a highly reliable process and it is as relevant today as it was when first conceived in the 1950s. It is one of the most versatile manufacturing process in terms of the number of materials that can be processed in a CNC machine - plastics, wood, metals, ceramics and many more.

In addition, Xcentric employs 3D printing to enhance efficiency, minimize waste, and reduce costs by utilizing only the necessary amount of material for each part. This approach facilitates on-demand manufacturing, proving particularly advantageous for small-scale injection molding or niche products. Committed to delivering superior service and products, among many bespoke injection molding manufacturers, Xcentric Mold & Engineering continuously explores new technologies and techniques to stay at the forefront of innovation.

Using 3D printed molds as an alternative to metal molds in injection molding is a fairly new process. As the quality and surface finish of 3D Printing continuously improves, 3D Printed molds for low volume injection molding are being pioneered by companies like Stratasys with their Polyjet printing and Formlabs using their SLA printers.

Setup costs involved in CNC machining, especially for complex geometry, are higher than that of 3D Printing. It is therefore more suited for low to mid-volume production (upto a few hundred parts depending on part geometry) with fast turnaround times as opposed to one-off production.

3D printed parts inherently have a 'layered' surface due to the way 3D printing works. But this surface can be sanded and painted to achieve the desired surface finish.

It should be noted that the cost-effectiveness of manufacturing process at a certain volume is highly dependent on the part geometry. For quantities approaching 300-500 parts, injection molding with lower quality steel or aluminum molds can be considered depending on the part geometry. It is a good idea to involve suitable engineering or manufacturing professionals who can guide you early in your product development process.
