Aerosol Packaging Container Material-Rolled Coil Iron 2019-09-11

Nowadays, with the development of the industry, more and more Iron raw material source are being developed and used. Iron as one of  the most important sources in the world, which is renewable resources, also non-renewable. Iron are actually different forms of metallic iron in nature. Natural metallic iron exists on the earth in the form of iron oxide, namely iron ore.  However, the earth's iron ore reserves are certain, the less mining. Iron ore like our country can no longer meet the needs of our huge metallurgical industry, importing 60% of the demand from Australia, Brazil, Peru, India and other places every year has become a major means of resource-occupying countries to restrict us.

tinplatetin cans

Iron, as the main important material of the aerosol packaging cans. Guangdong Sihai company need to purchase plenty of tinplate every year. We can produce various kinds of empty aerosol tin cans for industry packaging products and personal caring products and household products and car cleaning products etc.

Normal Thickness: 0.17mm, 0.18mm, 0.19mm, 0.20mm, 0.21mm, 0.23mm, 0.25mm, 0.28mm, 0.32mm, 0.35mm, 0.40mm, 0.43mm.

Normal Hardness: T3 BA/CA,  T4 BA/CA

Quality Inspection:

There are many items in steel quality inspection, including tensile test, bending fatigue test, compression/bending test and corrosion resistance test. Material and related products in the R&D and production process to grasp the real-time product quality and performance, can avoid quality returns, waste of raw materials and so on.

Surface Quality:

  • No inclusions, cracks, rusts and other harmful defects are allowed on the surface of steel plate or strip, and no parking spots are allowed. Defects that do not affect the moulding properties are allowed, such as slight non-palpable scratches, light yellow film after pickling, slight pitting, scratches, roll prints and indentations, chromatic aberration and slight non-palpable wrinkles, etc.
  • Since there is no chance for the strip to remove the defect, delivery with defect is allowed, but the defect does not exceed 6% of the total length of the coil.
  • Oiling refers to the electrostatic rust-proof oil with certain rust-proof properties coated on the surface of steel plate, which is lightly, moderately and heavily oiled, as specified by the buyer in the contract. The supplier shall ensure that the oil-coated products are free from rust within 3 months under normal transportation and storage conditions.

Acceptance Criteria

  • Tensile test and bending test are suitable for longitudinal specimens.
  • The specimens L0=50 mm and b=25 mm were used in the tensile test.
  • Sampling scheme of bending test should be carried out according to sample No. 3 of JIS Z 2204 and test method should be carried out according to JIS Z 2248.
  • Hardness test is carried out in accordance with JIS Z 2245.
  • HRB target value of hardness is 60 + 8. The actual value provided in the warranty is not required for acceptance.
