All GruberTech Equipment for Composites Manufacturing Applications

For continuous matrix production and dispensing of Polymer Concrete, Cultured Marble and Solid Surface

The Autocaster™ series of continuous casting systems automate the production of polymer matrix for cast polymer manufacturing. Replacing manual mixing with the Autocaster machine can significantly increase productivity, cut material cost and improve quality all leading to increased for the manufacturer. Useful for a variety of composites manufacturing applications, including cultured marble, densified solid surface, polymer concrete, and other composites manufacturing applications:

Autocaster Series Continuous Casting Systems

Autocaster™ systems include:

  • Autocaster Ultra - for automated production of cultured marble, cultured granite and cultured onyx

  • Autocaster Economizer - a lower output, less feature-intensive, more economical Autocaster continuous casting machine for those small and medium sized marble shops that don't need the capability of the Autocaster Ultra series.

  • Vacuum Autocaster Ultra - for automated production of densified solid surface matrix

  • Autocaster Ultra/PC (Polymer Concrete) - specific to production of polymer concrete


Gantries, Bulk Bag Suspenders, Bulk Bag Roller Conveyors and more.

Ground Hoppers

Gruber Ground Hoppers

Meter and Convey bulk fillers for cultured marble, solid surface, polymer concrete and more. Efficiently meter and convey bulk fillers of all types to the point of use (usually a Gruber Autocaster or other continuous casting system).

Bulk Bag Suspender Frame

Bulk Bag Suspender Frame

The optional Bulk Bag Suspender Frame allows the option of mounting larger, more economical bulk bags (“Super Sacks”) above Gruber’s Ground Hopper™ bulk solids conveyors. Mounting large bulk bags reduce interruptions during the manufacturing process, and reduces labor costs normally associated with manual loading of a metering or feed hopper – particularly when compared to manual loading of smaller bulk material bags.

Bulk Bag Gantry

Bulk Bag Gantry

Bulk Bag Gantries are used to lift Bulk Bags (aka Super Sacks) into position over a Ground Hopper. Two sizes are available.

Bulk Bag Roller Conveyor

Bulk Bag Roller Conveyor

Bulk Bag Roller Conveyors facilitate the movement and storage of pallets containing bulk bags (super sacks) from a fork-lift access point to a Bulk Bag Gantry (also available separately).


Equipment for metering of raw materials, powders/bulk fillers, and blended cultured marble or solid surface matrix.

Batchmaster III Metering System

Batchmaster III Metering System

Automated metering and batch mixing of cast polymer matrix

The third generation Batchmaster III provides the best features of weight-based and volumetric metering systems in a single system that is the most flexible and reliable on the market. It provides recipe-based, automated batch mixing cultured marble, cultured onyx, solid surface, or other cast polymer matrix, which is conveniently dispensed out of a barrel.

Featuring heavy-duty, professional quality Marble Blenders, Solid Surface Vacuum Mixers, and other tools like Bung Agitators for the production of cast polymer matrix.

100LbBlender150

Marble Blenders

Thoroughly and automatically mix cultured marble matrix and other materials with this line of heavy-duty blenders.

Model GS1000 Vacuum Mixer

Vacuum Mixers

Gruber Systems' Vacuum Mixers effectively evacuate air from the matrix during the matrix blending process, to produce void-free cast solid surface products. Vacuum mixed materials are condensed, void-free, durable products that can be fabricated to create popular designs in today's kitchen and bath market.

Bung Agitators

Bung Agitators

Binks Bung Agitators are easy-to-use high torque mixers with collapsible blades allowing insertion and extraction through the standard 2 in. bung in closed-top 55 gallon containers. During rotation, centrifugal force causes the blades to open.


Vibration Tables

Vibe Tables are essential shop equipment to help fill all voids in a mold during casting. As the mold is being filled, the Vibe Table vibrates, settling uncured matrix to completely fill the mold. This is a must-have for any cultured marble or solid surface manufacturer!

Quickly and efficiently cure gel coat sprayed molds with Gruber Gel Coat Curing Tunnel and Variable Speed Curing Tunnel. Post Cure cast cultured marble or solid surface product for added part strength with Gruber Post Cure Rooms.

Gel Coat Curing Tunnel

Gel Coat Curing Tunnel

Accelerate the cure time for gelcoated molds by more than 50%* (your experience may vary depending on conditions), while at the same time enabling a better, more durable cure.

Variable Speed Gel Coat Conveyor/Tunnel (VSGT)

Variable Speed Gel Coat Conveyor/Tunnel (VSGT)

Precise and automatic movement of molds through the gelcoat curing process. By automatically moving the molds through the tunnel, labor associated with mold moving can be reduced and precise gelcoat cure times can be obtained.

Post Cure Heat Room

Post Cure Heat Room

The Post Cure Heat Room is designed to accelerate the complete polymerization (curing) of solid surface panels and other cast parts prior to finishing.


Often called Casting Carts, this includes any carts that move, transfer or position molds in a production line. Gruber manufactures dozens of casting carts and tables - which are used to simplify movement of molds and castings through the production process - or to position molds accurately for use in continuous casting processes.
