Autocaster Continuous Casting Systems

Developed specifically for Polymer Concrete manufacturing applications.

Autocaster/PC Polymer Concrete Continuous Casting System

The Autocaster Ultra/PC (Polymer Concrete) edition system automates the production of polymer concrete matrix for cast polymer concrete manufacturing of a variety of durable cast products.

Replacing manual mixing with the Autocaster/PC (Polymer Concrete) Edition system can significantly increase productivity, cut material costs and improve quality - all leading to increased profits for the manufacturer. Our many years of experience with continuous casting machines and cast polymer manufacturing equipment have led to innovative improvements that have been incorporated into this purpose-built Autocaster specially designed for production of polymer concrete cast products.

Now choose from three different polymer concrete Autocaster machines - depending on your needs!

Assuming 7 hours/day of casting in an 8 hour shift, produce well over 200,000 lbs (95,000 kg) in a single shift! with the 500 lb/minute machine)

Provided with the base unit are three filler metering systems, one resin metering system, one catalyst metering system, and one base-color metering system. Additional raw material systems can be supplied as needed.

System Features:

  • Choose from three mixing system configurations depending on your output needs:
1)  30 – 100 lb (15 - 45 kg) per minute
2)  100 – 250 lb (45 - 115 kg) per minute
3)  250 – 500 lb (115 - 225 kg) per minute
  • PLC based recipe control system with on-the-fly matrix adjustments for resin %, catalyst % and matrix output

  • Expandable Base Color system (1 color standard) - option to add more (4 maximum)
  • High-efficiency, easily replaceable tungsten carbide coated separate component mixing auger and case hardened mixing barrel

  • Precise filler metering with three (3) included Filler Metering Hoppers (note: can be configured with more or fewer hoppers)

  • Accurate filler metering augers with integrated anti-bridging devices

  • Inverter-controlled motors for accurate delivery of raw materials
  • Resin system with integrated inline resin heating system

  • Totalizer for all raw materials

  • Precision gear pumps for resin, catalyst and base-color

  • Compact footprint for tight production areas.

Polymer Concrete Machine Related Options:

  • Additional Standard (Powder) Filler Metering Hopper – Three metering hoppers are standard (on 1000PC3H above), but you can mix and match between powder and aggregate Filler Metering Hoppers to suit your needs.  Choose from Powder (#UCFMH), Small Aggregate (#163735) or Large Aggregate (#163715). Can be configured with fewer than three as well if not all three are desired.

  • Add additional Base Color - One Base Color is included in the standard configuration, but you can add additional base colors with this option. To add 1 additional Base Color (#CMBCS-1C), to add 2-Colors (#CMBCS-2C), to add 3-Colors (#CMBCS-3C)

  • Fiberglass Strand Chopper - Reinforce your cast part with this automatic Fiberglass strand chopper system. Automatically cuts 1-1/2” strands of fiberglass from a roll, and adds it to your matrix. Choose full or partial speed motor - #700CA

  • Expanded Resin Heating Option - In cold climates, or given particular matrix/resin percentages, we recommend the expanded inline resin heater option - #163500

  • Cobalt Promoter System – Use of a promoted resin is highly recommended. If using an unpromoted resin, then the Cobalt Promoter System Option is required - #151000

  • Remote Batch Display – matrix batch meter with run-time reset - #162966

  • Remote Operator Interface Terminal (OIT) – Replaces the standard arm-mounted control panel with a remotely located pedestal-mounted OIT. This also removes the arm and OIT from the machine - #1500ACB-R
