Fast Heat

What Fast Heat does

Fast Heat, operating under Spark Industries LLC, designs and manufactures hot runner temperature controllers and supporting diagnostic equipment for the injection molding industry. The company sells three controller lines — the flagship Pulse (30-180 zones), the patent-pending modular MOD24 (up to 192 zones, scheduled for 2026 launch), and the ION — alongside patented MoldXChecker and CableXChecker diagnostic tools, SmartMold Box thermocouple protection, heavy-duty hot runner cables in DME, Fast Heat, and Husky configurations, and a repair/rebuild service program. Core technology centers on an 8.33ms-resolution adaptive PID control algorithm, supplemented by proprietary features including Waterfall Technology (up to 67% peak kW demand reduction via staggered heater cycling), EvenSoak sequential startup (to protect tooling from uneven thermal expansion), and Active Thermocouple Protection. Two granted US patents protect the diagnostic tools, with a third pending on the MOD24 architecture.

The business serves injection molders across automotive, appliance, consumer goods, medical, military, packaging, and industrial verticals, with named customers including Advanced Drainage Systems, Becton Dickinson Biosciences, Marathon Special Products, Rehrig Pacific, Cavaform International, and Revere Plastics. Go-to-market is sales-led for enterprise controllers (quote-based, with on-site appointments and free product trials) combined with direct e-commerce at fastheatbyspark.com for cables, spare parts, and diagnostic tools. Distribution is primarily North American with extension into the UK via a partner, and the company maintains active presence at major plastics and automation trade shows including PTXPO 2025 and NPE 2024.

Fast Heat's revenue model is hardware-driven: controller sales (zone-count-priced), diagnostic tools ($1,495-$2,075), cables ($430-$490), and spare parts ($295-$1,734), with a recurring repair-and-rebuild service stream. The company is privately held by its two co-founders, Chad Root (Sales & Administration) and Manny Diaz (Production & Engineering, inventor of the diagnostic patents), who founded Spark Industries in December 2020 to acquire the original Fast Heat product lines founded in 1957. Operations run from Elkhart, Indiana (administration) and Mokena, Illinois (production), with no institutional investment or public funding disclosed.

Product overview

Fast Heat by Spark Industries offers a comprehensive hot runner temperature control ecosystem for injection molding. The core product portfolio centers on three main controller lines: the Pulse™ (scalable 30-180 zones, featuring Waterfall Technology for up to 67% peak kW reduction and EvenSoak sequential startup), the MOD24™ (patent-pending modular controller with 6-zone plug-and-play modules scaling to 192 zones, supporting OPC-UA Euromap 82.2 and Industry 4.0 integration), and the ION™ controller series. These are complemented by the MoldXChecker® and CableXChecker® diagnostic tools (patented troubleshooting devices that prevent line-down situations) and the SmartMold Box™ (thermocouple protection unit). Supporting products include heavy-duty hot runner cables in DME®, Fast Heat Standard, and Husky® configurations, along with repair and rebuild services. Legacy offerings include Heated Sprue Bushings and Screw Tip Assemblies distributed through partner relationships. The company serves injection molders in automotive, medical, packaging, consumer, appliance, military, and logistics industries.
