Drawing-driven conversion
Custom die-cut foam and adhesive components, built from your drawing
We convert EPDM, EVA, PE, XPE, IXPE, and PU foam into sealing, gasket, and sleeve components sized and profiled to your specification.
Product families
Four categories, drawing-matched to your application
The complete HAI HONG catalogue contains 22 customer-supplied product families. Open a family to compare the documented materials and applications.
Application sectors
Core focus in HVAC, electronics, and packaging
HAI HONG's current core applications are HVAC and refrigeration equipment, sensors and electronic instruments, and protective packaging. We also support processing for the additional sectors below.
HVAC & refrigeration equipment
Insulation pads, pipe sleeves, and foam gaskets for HVAC and refrigeration assemblies.
Sensors & electronic instruments
Sealing pads, sleeves, and adhesive die-cut parts for instrument and sensor housings.
Protective packaging
Foam inserts and cavity trays that hold and protect finished components in transit.
Energy equipment
Foam and adhesive components processed for energy equipment assemblies.
Automotive components
Converted foam parts processed for automotive component applications.
Appliances
Foam pads and gaskets processed for appliance assembly requirements.
Industrial equipment
Custom-cut components supporting general industrial equipment assembly.
Building HVAC ducts
Composite insulation pads processed for building HVAC duct sections.
Manufacturing capability
A verified 5,000 m² facility running five production lines
The current Henan company was established in 2018, continuing a predecessor operation founded in 1995. Around 50 employees run coating, cutting, hydraulic pressing, CNC die cutting, vertical cutting, slitting, and basic physical-performance inspection across five production lines.

Custom conversion process
Every component is built to your drawing, not a catalogue spec
HAI HONG does not sell off-the-shelf sizes. Production starts once your drawing or sample confirms the profile.
- 01
Drawing or sample submitted
You send a technical drawing, CAD file, or physical sample with the dimensions and tolerances required.
- 02
Material & process confirmed
We confirm foam or adhesive material, thickness, and the coating, cutting, or pressing process needed to meet it.
- 03
Converted on our lines
Coating, hydraulic pressing, CNC die cutting, vertical cutting, and slitting equipment convert the material to your profile.
- 04
Basic performance inspection
Finished parts pass a basic physical-performance check against the confirmed specification before packing.
- 05
Packed & dispatched
Approved parts are packed to protect the finished profile and dispatched against your order.
Quality approach
Inspection built into the conversion process
Quality control begins at material sourcing and continues through cutting, pressing, and final inspection.
Drawing-matched dimensions
Parts are cut and pressed against the dimensions confirmed in your drawing or sample, not a fixed catalogue size.
Basic physical-performance inspection
Converted parts undergo basic physical-performance inspection on the production floor before packing.
RoHS / REACH supported materials
The foam and adhesive materials we source are supported by RoHS and REACH reports from our material suppliers.
