Question 1

What is an insulation jacket for plastic processing machines?

Accepted Answer

An insulation jacket is a removable, multilayer thermal cover that wraps around the barrel, heater bands, die head and hot zones of injection molding, extruder, blow molding and recycling machines. IHEAT IWRAP jackets trap radiated heat inside the barrel, reducing electricity consumption of heaters by 20–35% and cutting external surface temperature from ~160°C down to ~45°C.

Question 2

How much energy can IWRAP insulation jackets save?

Accepted Answer

IWRAP jackets typically save 20–35% of heater electricity consumption on injection molding, extruder and plastic processing machines. Real customer sites in Ahmedabad and across India report 25–30% average kWh reduction, verified through pre and post installation power meter readings and ROI calculators.

Question 3

What is the payback period or ROI of an insulation jacket?

Accepted Answer

Typical ROI for IWRAP insulation jackets is 3–4 months for injection molding and extruder machines running 20+ hours a day. High-tonnage machines with continuous operation see payback in as little as 2 months. Our online ROI calculator (iheat.in/roi-calculator) gives an exact estimate based on your heater load, kWh rate and operating hours.

Question 4

Are IHEAT insulation jackets removable and reusable?

Accepted Answer

Yes. IWRAP jackets are 100% removable and reusable. They are secured with heat-resistant velcro and stainless steel D-rings so operators can quickly remove them for heater servicing, temperature calibration or barrel cleaning, and refit them in minutes without any specialist tools.

Question 5

How much does the surface temperature reduce after installing IWRAP?

Accepted Answer

Surface temperature reduction is typically 70–80%. On a 350T injection molding machine barrel running at 160°C, IWRAP brings the outside touch temperature down to ~45–55°C — improving worker safety, reducing air-conditioning load and stabilising melt temperature.

Question 6

Are IWRAP jackets compatible with Haitian, Yizumi, Shibaura and other machine brands?

Accepted Answer

Yes. IWRAP jackets are custom-engineered for every major injection molding, extruder and blow molding brand including Haitian, Yizumi, Shibaura, Milacron, Engel, Arburg, Windsor, Sumitomo, Electronica, Fanuc, JSW, Bole, Supermac, Pasl, FCS, JHwelltec and Parth. We manufacture to your exact barrel OD, length and heater configuration.
