About C-Tech Laboratory Equipment Co., Ltd - Industrial Machinery Supplier in China

C-Tech Laboratory Equipment Co., Ltd is based in China and currently lists six active products in its catalogue. The catalogue spans Industrial Machinery, Dies & Mouldings, and Laboratory Equipments & Instruments, reflecting a focus on testing and moulding equipment. Products include the Los Angeles Abrasion Machine and the Micro Deval Abrasion Testing Machine, both used for aggregate abrasion testing. The Concrete Block Mould/Concrete Barrier Lego Mould is recorded under HS code 8480.41 and is fabricated from high‑strength alloy tool steel. The Concrete Test Mould/Concrete Cube Mould carries HS code 9024.80 and is made from cast iron or hardened steel grade FG 200 / EN1B. Additional items are the Skid Resistance and Friction Tester and a multi‑material test machine for concrete, soil, asphalt and rock.

The Los Angeles and Micro Deval machines conform to ASTM C131 and C535 test methods, which are standard procedures for evaluating wear resistance of aggregates. The skid resistance tester is typically employed to measure the French Pendulum Test (ASTM E303) for pavement surfaces. Moulds for concrete blocks and cubes are designed to meet EN 206 specifications for dimensional tolerance and surface finish. The multi‑material test machine integrates load cells and displacement sensors that are common in ISO‑9001 calibrated laboratory rigs. All listed equipment is classified under HS chapter 84 for machinery and chapter 90 for measuring instruments, aligning with international customs coding.

Product Range and Specialties of C-Tech Laboratory Equipment Co., Ltd

C-Tech’s product line includes two abrasion testing machines, a skid‑resistance tester, a versatile test machine for concrete, soil, asphalt and rock, and two concrete mould types. In the abrasion sector, Los Angeles and Micro Deval machines are usually specified with a test speed of 30 rpm and a sample size of 500 g, delivering results in percent mass loss. Industry standards such as ASTM C131, C535 and ISO 13370 define the acceptable range of abrasion loss between 0 % and 15 % for most road‑construction aggregates. Concrete moulds are commonly fabricated from high‑strength alloy tool steel or cast iron with hardness above 45 HRC, matching the FG 200 / EN1B grade noted for the listed moulds. Typical dimensions for standard concrete cube moulds are 150 mm × 150 mm × 150 mm, and for block moulds they range from 190 mm × 190 mm × 190 mm up to larger modular units. Skid resistance testers are calibrated to the French pendulum standard, delivering a friction value expressed in pendulum numbers (PN) from 20 PN to 70 PN. The multi‑material test machine often incorporates interchangeable fixtures and can handle load capacities from 5 kN to 200 kN, fitting the needs of civil‑engineering laboratories. Export‑ready units are typically packed in wooden crates with internal cushioning, and dimensions allow container loading of up to four units per 40‑ft container depending on model size.

Trade and Export Information - C-Tech Laboratory Equipment Co., Ltd

Chinese manufacturers of laboratory and testing machinery commonly ship to Europe, North America, the Middle East and Southeast Asia, where infrastructure projects drive demand for abrasion and concrete testing equipment. HS code 8480.41 falls under chapter 84 (machinery for working of metal) and is subject to import controls that may require a CE declaration of conformity in the European Union. HS code 9024.80 belongs to chapter 90 (optical, photographic, measuring, checking instruments) and often necessitates a Type‑Ex certification for safety in many jurisdictions. Buyers typically request ISO 9001 quality‑management certification, CE marking, and, for the United States, compliance with ASTM standards and FDA‑recognised calibration reports when applicable. Standard Incoterms for these heavy equipment shipments are FOB Shanghai or CIF destination port, with containerized transport preferred for the moulds and larger test machines. Due to the size and weight of the test machines, manufacturers use 20‑ft or 40‑ft containers with internal bracing to prevent movement, and the moulds are often loaded on pallets with shrink‑wrap. Export documentation routinely includes a commercial invoice, packing list, certificate of origin, and where required, a third‑party inspection report such as SGS or Bureau Veritas. Regulatory bodies in importing countries may inspect the equipment upon arrival for compliance with safety standards and correct HS classification.

Sourcing from C-Tech Laboratory Equipment Co., Ltd - Buyer Guidance

Prospective buyers should request the latest calibration certificates and test reports that reference ASTM C131, C535 or ISO 13370 for the abrasion machines. Material certificates confirming the alloy composition of the tool‑steel moulds and the hardness of the cast‑iron cube moulds (FG 200 / EN1B) help verify durability. Ask for CE Declaration of Conformity and ISO 9001 certification to ensure the supplier follows recognized quality‑management practices. Verify the HS codes (8480.41 for the block mould and 9024.80 for the cube mould) match the product description in the purchase order to avoid customs delays. Typical minimum order quantities are one unit per machine model, with moulds often ordered in batches of ten to optimise container space. Lead times reported by Chinese manufacturers for these types of equipment range from 30 to 60 days after receipt of a confirmed purchase order and required test documentation. Ensure that packaging specifications include wooden crates with internal padding and that the shipment is insured for the full equipment value.

What types of abrasion testing machines does C-Tech offer?

C-Tech lists the Los Angeles Abrasion Machine and the Micro Deval Abrasion Testing Machine, both designed to evaluate aggregate wear according to ASTM C131 and ISO 13370. The machines operate at standard speeds of 30 rpm and provide mass‑loss results expressed as a percentage.

Which HS codes are associated with C-Tech’s concrete mould products?

The Concrete Block Mould/Concrete Barrier Lego Mould is classified under HS code 8480.41, while the Concrete Test Mould/Concrete Cube Mould uses HS code 9024.80. These codes correspond to machinery for working of metal and measuring instruments respectively.

What material specifications are provided for the concrete moulds?

The block mould is made from high‑strength alloy tool steel, and the cube mould is produced from cast iron or hardened steel meeting grade FG 200 / EN1B, typically delivering a hardness above 45 HRC. These materials are selected to withstand repeated compression testing without deformation.

What certifications should a buyer request for these testing machines?

Buyers should request a CE Declaration of Conformity and ISO 9001 quality‑management certification. In addition, calibration certificates that reference the relevant ASTM or ISO test standards should be supplied before shipment.

What is the typical packaging and shipping method for the test machines?

Machines are normally packed in reinforced wooden crates with internal bracing to protect moving parts. They are loaded into 20‑ft or 40‑ft containers and shipped under FOB Shanghai or CIF to the destination port.

What are the common quality parameters buyers verify for the skid resistance tester?

The skid resistance and friction tester is calibrated to the French Pendulum Test (ASTM E303) and provides readings in pendulum numbers (PN) from 20 PN to 70 PN. Buyers usually verify measurement repeatability of ±0.5 PN and ensure the device carries a CE marking.

What lead time and minimum order quantity does C-Tech usually require?

Typical lead times are 30‑60 days after order confirmation and receipt of required test documentation. The minimum order is one unit per machine model, while moulds are often ordered in multiples of ten to maximise container utilisation.
