Repeated testing on various stages of every batch throughout the manufacturing process enables us to ensure quality and safety of our products. On average, a batch is tested six times. Every week our Technical staff in our full-scale quality control laboratory perform as many as 1,000 tests on raw materials, in-process product batches, and finished product.Arising in Industry :
Lumps Too Fine :Â Â Plasters will create lumps during paste preparation.
Inconsistency :Â Â Inconsistency of plaster setting time.
Lower productivity and inconsistent quality of molds.
Fragile Molds :Â Â Low bending strength plasters will produce molds that do not resist tough handling by workers.
Short Mold Life :Â Â Low mechanical strength plasters yield too low mold surface hardness.
Cracks :Â Â Plaster that expands or shrinks too much will make cracks on surface.
Fast Setting Time :Â Â Too Fast Setting Time of Plaster : means not enough time to release bubbles, which results in lower strength, so risks of breakage during the handling of molds.
Long Drying Time :Â Â Plaster with bad porosity will bring too long drying time of molds after usage.
Surface Problems :Â Â Hard particles in plaster will destroy surface of your product.
High Iron Content :Â Plaster will create black spots on clay ware.
Set Plaster Lumps :Â Plaster badly protected from moisture will have lumps that will destroy surface of clay ware.
