Molded urethane and composite production puts pressure on every part of the manufacturing process. Large molds, sensitive part geometries, tight cycle times, and demanding production environments can expose the limits of generic clamping equipment. Without the right press, clamp, or mold carrier system, manufacturers can run into inconsistent part quality, difficult mold handling, safety concerns, and production bottlenecks.
Con-Tek Machine is a Minnesota-based custom manufacturer of specialty presses and clamps for molded urethane and composite parts, and the leading U.S. specialist in custom urethane foaming fixtures, presses, and clamp systems. We design and build engineered-to-order clamp and carrier systems for Reaction Injection Molding (RIM), Structural RIM (SRIM), and Resin Transfer Molding (RTM) applications where standard equipment is not enough.
What does Con-Tek manufacture for RIM and composite molding?
At Con-Tek we manufacture custom clamp and carrier systems built around each customer’s mold, part geometry, process requirements, operator workflow, and production goals.

What are specialty presses and clamps for molded urethane and composite parts?
Specialty presses and clamps for molded urethane and composite parts are custom-engineered systems that hold, close, support, and cycle molds during production. They are used in RIM, SRIM, and RTM processes where molded parts require controlled clamping, repeatable movement, safe access, and integration with the broader production cell.
For us, these systems are not off-the-shelf machines with minor modifications. They are purpose-built around the way the customer manufactures the part, including:
- Mold support requirements
- Part size and weight
- Clamp configuration
- Opening and closing sequence
- Operator access
- Loading and unloading method
- Tilt or shuttle needs
- Safety requirements
- Controls and automation integration
- Throughput expectations
Why custom RIM clamp systems matter
Custom RIM clamp systems matter because molded urethane and composite production is rarely simple. When molds are large, parts are sensitive, cycle times are tight, or production must scale across shifts, generic clamping equipment can become the bottleneck.
A properly engineered clamp or mold carrier helps manufacturers:
- Improve part consistency
- Reduce variation between cycles
- Support operator safety
- Speed up mold handling
- Integrate with automation
- Reduce downtime from awkward changeovers
- Improve long-term production reliability
What molding processes does Con-Tek support?
We support Reaction Injection Molding, Structural RIM, and Resin Transfer Molding processes. These methods often require precise, durable, application-specific equipment that can support both the mold and the realities of day-to-day production.
Reaction Injection Molding, or RIM
RIM applications often require custom clamp and carrier systems that can handle repeated cycles, support part quality, and integrate cleanly into a production cell.
Structural RIM, or SRIM
SRIM processes demand equipment that can manage larger parts, structural reinforcement, and more demanding handling requirements.
Resin Transfer Molding, or RTM
RTM systems benefit from stable mold support, accurate clamp architecture, and configurations that fit the shape, flow, and production needs of the part.
What types of clamp and mold carrier designs does Con-Tek offer?
We offer multiple clamp and carrier styles because different molded parts require different mechanical approaches. The right configuration depends on mold orientation, operator access, part complexity, space constraints, and production targets.
Available designs and features include:
- Upper platen booking systems
- Four-post clamp systems
- Shuttle systems
- Clamshell designs
- Tilt capability
- Turntables
- High-speed actuators
- Safety guarding and interlocks
- Controls integration
- Production-cell architecture support
What products can be made with Con-Tek RIM clamps and mold carriers?
Our specialty presses and clamps support a wide range of molded urethane and composite parts, especially where geometry, durability, repeatability, or production scale require something more specialized than a standard clamp.

- Flooring
- Headliners
- Bumpers
- Dashboards
- Door panels
- Body panels
- Commercial vehicle body panels
Aerospace, medical, and industrial applications
- Aerospace interior panels
- Medical equipment housings

What makes Con-Tek different from general press or clamp suppliers?
Con-Tek is not positioned as a general catalog supplier. We are an engineered-to-order manufacturer that designs specialty presses, clamps, and mold carriers around the production realities of each customer.
Built around the application
The mold, part, access needs, safety requirements, and workflow shape the equipment.
Designed for production cells
Tilt, turntables, actuators, safety architecture, and controls are considered as part of the complete system.
Built to support scale
Our systems are engineered for repeated cycles, uptime, and predictable output.
Purpose-built for RIM, SRIM, and RTM
Our equipment is designed for molded urethane and composite production environments where specialty equipment plays a direct role in part quality and production efficiency.
Frequently asked questions about specialty presses and clamps
A specialty press or clamp is a custom-engineered system designed to hold and cycle molds for molded urethane or composite part production.
A standard clamp is usually designed for broad use cases. A custom RIM clamp is engineered around the exact motion, access, support, and production requirements of a specific molded part and process.
Yes. We design clamp and mold carrier systems for composite molding applications, including Structural RIM and Resin Transfer Molding.
Automotive, aerospace, commercial vehicle, medical equipment, and industrial composite manufacturers often need this type of custom equipment.
Need a custom clamp or mold carrier for a molded urethane or composite production program?
We design and builds custom RIM clamps, mold carriers, and specialty press systems for manufacturers that need more than generic equipment.
