Flow Chart for Manufacturing Process

Choosing the optimum lead-free elements The radiation protection glove is manufactured in a complex operation that begins with choosing the right x-ray protective elements.

The optimum compounding of these elements is the key to a perfect glove.

Lead-free compounding Mixing and homogenization of the selected lead-free elements with natural latex in correct proportions is a very important process called Compounding.

A variable speed intensive mixer and homogenizer is used for this operation.

Surface preparation of porcelain formers A smooth and clean surface of formers is achieved by cleaning with acid solutions, cleaning agents and coating with wetting agents.

Formation of raw gloves Production of raw gloves in desired shape and size is carried out by dipping porcelain formers for a controlled time while monitoring various parameters in the leadfree compound.

These gloves are formed inside out so that the glove surface that comes in contact with user is on the outside and textured surface on the inside.

Protein removal

Additives such as accelerators and proteins are removed through hot leaching by intensive wash in hot water followed by heat drying.

Internal coating of hypoallergenic compound The surface of the glove which comes in contact with the user, is coated with hypoallergenic compound for better properties of donning, flexibility and skin care.

This is done by dipping semi-cured gloves under controlled conditions in a hypoallergenic mixture.

Beading After internal coating Gloves are beaded to provide a grip while donning, as well as to prevent roll back.

Curing of gloves Curing involves the cross linking of polymers with each other, and bonding with lead-free metal particles by heat treatment at controlled temperature and airflow in a specialty oven.

Inspection and testing Each piece of glove is visually inspected while a large percentage of production is tested for strength, attenuation, and dimensions.

Leak testing After removal from moulds, 100% of gloves undergo a high pressure leak test.

Even a microscopic hole does not escape detection in this test.

Powder free All gloves are treated in a sophisticated chlorination chamber to eliminate the need for powdering them, as well as to lower the protein levels to minimum levels.

Finishing Gloves are inspected, printed and packed in specially designed finishing rooms, under HEPA filtration and in Clean Room environment .

Controlled environment for finishing

Packing Gloves are sealed using high speed automatic vacuum sealing equipment, which perfectly maintains the seal strength and vacuum.

Automatic pouch sealing

Sterilization Gloves are Gamma sterilized as per guidelines of ISO 11137-2006 with a minimum dose of 25 kilo Gray to result in a perfectly sterile glove.
