Meeting DOT Standards with Custom Slat Conveyor Oven

A Tier 1 automotive supplier needed three slat conveyor ovens to perform thermal testing on occupant safety-related components. The ovens needed to meet stringent U.S. Department of Transportation (DOT) standards to ensure product compliance, reliability, and safety. The customer also needed equipment that could integrate seamlessly into their existing production environment while supporting high-volume testing operations.

HeatTek designed and manufactured three custom electric Slat Conveyor Ovens that were specifically engineered to meet the DOT requirements. Each oven featured two independent heating zones for precise temperature control, followed by a dedicated cooling zone to stabilize parts before handling. The ovens were capable of heating products to 100 °C and maintaining that temperature for a minimum of 30 seconds to ensure proper thermal conditioning.

To maximize efficiency and safety, the systems included indexing slat conveyors for controlled part movement, vertical lift doors for improved access, and quick-change slat tooling for fast product changeovers. A touchscreen operator interface allowed for simplified control and monitoring. Safety features such as light curtains and enhanced guarding were integrated to protect operators during operation and maintenance.

With the new conveyor ovens, the Tier 1 automotive supplier achieved reliable, repeatable thermal testing while maintaining full compliance with DOT standards. The precise temperature control improved test consistency, while the indexing and quick-change features reduced setup time between product runs. The enhanced safety systems provided a secure work environment without slowing production, and the robust oven design supported continuous operation in a high-demand manufacturing setting. This solution not only met the customer’s compliance needs but also improved overall testing throughput and operational efficiency.
