TEX Plastics Invests in Advanced Robotic Sealing Technology at Derby Facility
27 July 2026
New automated DOPAG system will improve efficiency, increase production capacity and reduce environmental impact.
Continuing Investment in Manufacturing Excellence
TEX Plastics has announced a major new investment at its Derby facility with the introduction of a fully automated robotic sealing system from DOPAG UK, due to arrive in mid-July.
The new equipment forms part of the company’s ongoing investment programme focused on improving operational efficiency, increasing manufacturing capacity and reducing the environmental impact of production processes across the business.
The system will support the manufacture of components used within several specialist sectors, including:
- Water heating systems
- Industrial catering equipment
- Traffic control systems
As a leading UK technical injection moulding specialist, TEX Plastics continues to invest in advanced automation technologies that help strengthen production capability while supporting long-term sustainability objectives.
Replacing Energy-Intensive Oven Curing Processes
The new robotic sealing system represents a significant improvement over the existing sealing process currently used within production.
At present, seals applied to moulded components require oven curing after application. While effective, this process is both time-consuming and energy intensive, requiring additional production stages, increased handling and extended curing times before components can move further through manufacturing.
The current curing process also limits the total number of seals that can be completed during a production shift.
The new DOPAG system removes this bottleneck by introducing a chemically curing sealing process that eliminates the need for oven curing entirely.
Instead of relying on heat and extended curing cycles, the new sealing material cures through chemical reaction immediately after application. This allows components to move through production more quickly while significantly reducing energy consumption associated with heated curing systems.
Fully Automated Robotic Application Improves Consistency
The investment also introduces a fully automated robotic application process, delivering higher levels of precision, repeatability and process control.
DOPAG specialises in automated metering, mixing and dispensing systems for industrial bonding, sealing and gasketing applications, with technologies designed specifically for high-precision manufacturing environments.
According to DOPAG, automated dispensing systems offer:
- Precise and reproducible application results
- Reduced material waste
- Improved process stability
- Higher production efficiency
- Integration into automated manufacturing workflows
- Reduced operator intervention
- Greater consistency in quality-critical applications
The robotic sealing system installed at TEX Plastics will automate the metering, mixing and application of sealing materials, helping ensure highly accurate and repeatable sealing performance across production batches.
This level of automation is particularly valuable in technical injection moulding applications where sealing integrity, dimensional consistency and component reliability are critical.
Improving Sustainability and Reducing Carbon Footprint
One of the key drivers behind the investment is the environmental benefit delivered by the new technology.
By removing the need for energy-intensive oven curing, TEX Plastics expects to significantly reduce energy consumption associated with the sealing process.
The move aligns with the company’s wider sustainability and efficiency strategy, which focuses on reducing waste, lowering energy usage and improving manufacturing efficiency throughout the business.
Automated sealing systems also help reduce material overuse by delivering highly controlled and accurate dispensing of sealants and gasketing materials. DOPAG notes that automated systems are specifically designed to minimise waste while improving production consistency.
Additional sustainability benefits include:
- Lower electricity consumption
- Reduced process time
- Fewer production delays
- Reduced handling and transportation between curing stages
- Improved manufacturing throughput
- Reduced material wastage through precision application
For customers increasingly focused on supply chain sustainability and environmental responsibility, investments like this further strengthen TEX Plastics’ position as a forward-thinking UK manufacturing partner.
Increasing Production Capacity and Operational Efficiency
Alongside environmental improvements, the new system is expected to deliver substantial operational gains.
Because the chemically curing process eliminates waiting time associated with oven curing, production throughput can increase significantly. Components can move through the manufacturing process faster, allowing more seals to be completed during each production shift.
Automation also improves manufacturing flexibility by reducing manual intervention and helping maintain consistent production speeds throughout longer runs.
DOPAG’s automated dispensing technologies are widely used across industries requiring high-volume, high-precision sealing applications because of their ability to deliver repeatable results with shorter cycle times and improved process reliability.
For TEX Plastics customers, this investment helps ensure continued competitiveness, improved responsiveness and enhanced production capability within the UK manufacturing sector.
Supporting the Future of UK Technical Injection Moulding
The investment reflects TEX Plastics’ long-term strategy of combining technical expertise, advanced manufacturing technology and continuous improvement to support customers across multiple industries.
As manufacturing businesses face increasing pressure to improve efficiency, reduce emissions and maintain competitive lead times, automation and smart process improvements are becoming increasingly important.
By investing in advanced robotic sealing technology, TEX Plastics is continuing to strengthen both its operational capability and its environmental performance while reinforcing its reputation as a trusted UK technical injection moulding supplier with decades of industry experience.
The arrival of the new DOPAG system in July marks another important step in the company’s ongoing commitment to innovation, sustainability and manufacturing excellence.
