Raw Material Management

Our factory is located near the core raw material production areas, facilitating the acquisition of high-quality raw materials. Raw materials undergo two rounds of testing, ensuring double assurance of compliance with quality control standards.

Conveyance

Fully enclosed conveyor belt minimizes weathering loss.

Decontamination

Dual decontamination with 5000w electromagnetic iron and manual inspection reduces impurity content.

Filling

Automatic filling machine ensures accurate weight.

Sealing

Automatic sealing machine improves packaging sealability.

Nitrogen Filling

Nitrogen is injected into the steel drums while expelling the air inside. This reduces the amount of flammable gas within the drum, slows down the weathering process, and ensures safe storage and transportation.

Inspection

Each production stage is monitored by dedicated personnel.

Product Inspection and Warehousing

Finished Product Inspection: For every 10 tons of finished product, 15kg is selected from each size for testing to ensure the accuracy of the test results.

Packaging Inspection: Manual inspection ensures the integrity and appearance of each drum's seal.

Warehousing: Qualified products are stored in designated areas according to quality grades, while non-conforming products are returned for processing.

Other Quality Measures

System Establishment: A comprehensive quality management system, including quality manuals, standardized operating procedures, inspection records, and other documents.

Equipment Maintenance: Weekly equipment inspections and maintenance to ensure good and stable equipment performance.

Quality Control

Committed To Strict Quality Control, We Provide Stable And High-Quality Calcium Carbide.

1.Gas Yield

Conduct Finished Product Inspection According To 15KG/Ton/Size.

2.Size Percentage

Multiple screen combinations precisely control particle size through sieving.

3.Impurity

1500W electromagnet technology for the removal of iron impurities.Manual inspection

for impurities such as carbon rods and silicon iron.

4.Weight

Manual Electronic Equipment For Pre-Weighing, With A Dedicated Person To Verify the Weight.

5.Package

Dedicated Personnel Inspect The Seal Integrity Of Calcium Carbide Barrels.
