Cold Box Systems

HAI’s Phenolic Urethane Cold Box (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.

The PUCB process utilizes an amine gas to catalyze the reaction between a phenolic resin and an isocyanate resin to produce a urethane bond. No byproducts are produced; therefore curing takes place at the same rate throughout.

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

Advantages of the Cold Box Process

• High Productivity - Large volume high speed production
• 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. More Info

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
