FAQ

Common questions about IR drying for agricultural materials.


What information do you need for a quotation?

Share material, part size, target temperature, and cycle time—YFR engineers will recommend a suitable solution.








Which plastic processes benefit most from IR preheating?

How do l determine the required power for my drying line?

How do I avoid overheating or surface damage on plastics?

How do I set distance, dwell time,and power?

Does material type change the IR strategy (PP/ABS/PC/etc.)?

Short-wave vs medium-wave IR-what should I choose for plastics?

What controls or sensors are recommended?

Yes. Preheating parts or inserts reduces the heating demand inside the mold and can shorten overall cycle time when tuned correctly.

IR preheating is widely used for injection molding, thermoforming, compression molding,and preheating inserts/parts where fast response is needed.

Use staged power, appropriate heater distance, and zoning. Temperature monitoring and consistent part movement help prevent hotspots.

Start with a safe distance and moderate power, then tune based on target surface temperature and quality results at your required throughput.

Yes.Heat sensitivity and thickness vary by polymer. Selection and control strategy should be tuned per material and part geometry.

Short-wave responds quickly for fast lines; medium-wave can be gentler for heat-sensitive materlals or thicker sections.

Zoned power control is essential. Non-contact temperature measurement and recipe control improve repeatability across parts and materials.
