Cold Box

High Productivity - Large Volume - High Speed Production

Cold Box Process

The Phenolic Urethane Cold Box (PUCB) process utilizes an amine gas to catalyze the reaction between a phenolic resin and an isocyanate resin to produce a urethane bond.

HAI’s PUCB resins are the best in the business when it comes to high core strengths, long mixed sand bench life, humidity resistance, and release characteristics that can’t be matched.

Choose from established brands, quality ingredients, and a full line of refractory coatings, release agents, and metal cleaners.

Advantages of Cold Box

  • No tooling heat required
  • Cures at room temperature
  • Cost effective to run in comparison to heat cured systems
  • Low labor and energy cost
  • Good dimensional accuracy
  • Cores can be handled immediately
  • Cores can be cast almost immediately
  • Long resin shelf life

Sigmacure

HAI's leading cold box product line, SigmaCure, utilizes the Phenolic Urethane Cold Box (PUCB) process.

Foundries interested in productivity, using Phenolic Urethane Cold Box resins, appreciate the diversity of performance capabilities offered within the Sigma Cure product line.

If you haven’t tested one of the Sigma Cure products, you haven’t unlocked the productivity potential of your Cold Box operation.

Biocure

HAI's environmentally advantageous cold box product line, Biocure, is a new Low VOC Biodiesel solvent system based on methyl esters of vegetable oils.

Biocure shows a reduction in volatile emissions and improved process performance and may help you satisfy the permitting and emission requirements of the local regulatory agencies.

Betaset

The same breakthrough chemistry which produced the ALpHASET No Bake system, was subsequently developed to produce the BETASET Cold Box system.

The BETASET system uses vaporized methyl formate gas to achieve a fast Cold Box cure and can be applied to a highly automated environment, such as automotive component production.

The BETASET system offers improved casting quality and environmental factors.

Carbophen

HAI's newest Phenolic Cold Box resin, Carbophen, is a water based phenolic resin system cured using CO2 gas.

This environmentally friendly cold box product line contains no reportable formaldehyde and offers the lowest VOC and HAP emissions at pouring, cooling, and shakeout of cold box systems. Features include:

  • Low odor inside and outside of the foundry
  • No scrubber is required
  • Resin contains no nitrogen, sulfur or phosphorous
  • No lustrous carbon is formed
  • Good humidity resistance and Tensile Strength
  • No odor, non-flammable curing agent

3D Core Printing Furan Resin

HAI's newest cold box resin, Enviroset 3D Jet Resin, is a low viscosity thermosetting furan resin that has been specially manufactured for use in 3D core printing machines and is suitable for use with all types of metal.

This furan resin offers a number of features that set it apart from conventional furan resins on the market:

  • Contains no nitrogen
  • Low water
  • Non-reportable formaldehyde and phenol
  • Low viscosity
  • High tensil strength

Amine Catalysts

The PUCB process utilizes an amine gas to catalyze the reaction between a phenolic resin and an isocyanate resin to produce a urethane bond. HAI's amine catalyst product line, Sigma Cat, is designed for use with our entire line of phenolic urethane cold box resins.

HA International also offers our customers an environmentally conscientious alternative to PUCB scrubber solution waste disposal. With HARP, amine is recovered to virgin specifications using the latest innovations in process technology
