Application guide
Gas, diesel and electric heating systems for molds, hot presses, forming lines and industrial temperature control.
Published 2026-06-27
Gas, diesel and electric heating systems for molds, hot presses, forming lines and industrial temperature control.
For this application, Yigao reviews temperature target, heating medium, equipment layout, operating rhythm and site energy condition before recommending a practical product configuration.
Start with the press rather than heater power alone. Send platen dimensions and material, the number of platens, oil-channel drawings, starting and working temperatures, cycle time and required heat-up time. Identify whether each platen or group needs independent temperature control.
Compare the gas-fired thermal oil heater with diesel option and electric thermal oil heater using the same heat load and production schedule. Include available fuel or voltage, supply capacity, pipe distance and installation constraints. The final circulation and control arrangement requires review of the press manufacturer's oil-channel and operating limits.
For replacement projects, include the current heater nameplate, pump data, supply and return temperatures, control-zone layout and the reason for replacement. Describe slow heating or uneven platen temperatures rather than assuming a larger heater will solve them. Review the multilayer press heating reference for a related installation context; it does not establish performance for a different press.
Recommended products

Interactive selection tool
Use the calculator with your heat load, local tariffs and operating schedule before requesting a mold temperature control proposal.
Buyer FAQ
Choose the heat source from the required heat load, target temperature, heat-up time, operating hours, local utility conditions, exhaust route and maintenance requirements. Gas or diesel may suit a continuous high-load site with available fuel infrastructure; electric heating may suit a site with sufficient electrical capacity and favorable tariffs.
Provide mold or press dimensions and mass, thermal oil volume and grade, target and starting temperature, required heat-up time, production heat loss, oil flow, pipe length, operating hours, available fuel or voltage, installation space and destination-country requirements.
The same thermal-oil heating concept can be reviewed for different equipment, but the pump flow, heat load, oil volume, control zones, pipework, expansion arrangement and safety protection must be checked for the actual application. Do not select from temperature alone.
No. The calculator provides a conditional operating-cost estimate from the entered heat load, tariffs, efficiency assumptions and schedule. Final equipment selection and savings require verified process data, site utilities, heat loss, exhaust, control requirements and a written technical proposal.
Project-fit review
You do not need a finished equipment specification. Send the known duty, present operating issue or available drawing, and Yigao can identify which inputs are still needed before a model and quotation are confirmed.
