CUSTOM THERMOFORMING PROCESSES
Custom plastic thermoforming processes are a means of shaping thermoplastic sheet to conform
to the contour of a mold through the use of heat and pressure, either positive or
vacuum. Plastic is heated to predetermined temperature at which the plastic softens
but is below its melt temperature. It is stretched to cover the contours of a mold
with the use of vacuum and cooled to a temperature at which the thermoplastic becomes
rigid, thus retaining the shape of the mold. The formed part is then trimmed to
eliminate edges, decorated and/or fabricated into an end use article. The scrap
material is usually reground and reprocessed into usable sheet.
Pressure Forming: The 10% solution.Pressure forming means startup tooling costs as low as 10% of that required for the same injection molded project!
That's more than a claim; it's documented fact. 10% of the cost...a 90% savings. Any way you look at it, it's a strong argument for considering pressure forming for your next molding project. Add to that enormous cost savings a turnaround time of just 20% of injection molding...together with quality that rivals injection molding for finite detail and crispness...

Vacuum Forming: When cost is critical. Vacuum forming is characterized by extremely low tooling and parts costs. Like pressure forming, vacuum forming features sheets of virtually unlimited size heated to a point of maximum flexibility, then formed to a mold. Also like pressure forming, the air between the mold and the material is removed by a powerful vacuum as the heated plastic melds to the mold and takes on its new shape.

Twin Sheet Pressure Thermoforming: Double your options. For all the honors heaped on single sheet pressure forming, no conventional thermoforming can make a hollow part unless two halves are made separately and bonded together. Twin Sheet Pressure Thermoforming can make that same part in a single operation. Depending on part size and quantities, it can actually do the job much more economically than blow molding.

Secondary Manufacturing Processes:
Grimm Brothers Plastics offers a full spectrum of value-added services at a very attractive cost to the OEM, because all the operations take place at a central facility, reducing freight and handling costs.
5-Axis CNC Trimming Grimm Brothers Plastics relies on 5-axis CNC routers for complicated trim configurations. These high volume routers are fast, accurate and consistent and capable of trimming on all
faces of the part without the need to reposition the part midway through the process.
Secondary Assembly In an effort to provide best value in the completed part, Grimm Brothers offers (but is not limited to) the following secondary assembly procedures: ultrasonic welding, gluing, bonding, fastening, labeling, hardware installation, EMI/RMI shielding, and bar coding.
When your project requires assembling multiple parts into larger or more complex finished products, Grimm Brothers is up to the task.
Painting & Decorating With an in-house painting facility, parts can be molded, prepped, painted and shipped within hours after it is formed. Working with our OEM partners, the engineering staff at Grimm Brothers can recommend the painted finish that will be economical, durable and meet the cosmetic needs of the customer.
Because Grimm Brothers handles all painting in-house, we can ensure maximum control over color, gloss, and texture. But that's not all. Final decorating is accomplished through the application of labels and decals, silk screening, pad printing, hot stamping and other methods.
