Tooth Iran

hotel porcelain-toothpick holder

Hotel porcelain toothpick holders are manufactured from feldspathic porcelain with water absorption below 0.5 percent and a dense structure. The firing process is carried out at temperatures between 1350 and 1400 degrees Celsius. Final density ranges from 2.3 to 2.5 grams per cubic centimeter. Flexural strength is at least 80 megapascals, and surface hardness is approximately 6 on the Mohs scale. A transparent or colored glaze layer with thickness of 0.2 to 0.3 millimeters is applied. Typical dimensions are designed within 40 to 80 millimeters in height and 30 to 60 millimeters in diameter.

The structure consists of a cylindrical or conical body with a controlled opening to organize toothpicks effectively. Wall thickness is generally selected between 3 and 5 millimeters to balance strength and weight. Thermal shock resistance is evaluated within a temperature differential of 100 to 140 degrees Celsius. The glazed surface exhibits near zero porosity and chemical resistance within a pH range of 3 to 11. Dimensional tolerance for diameter is usually maintained within ±1.5 millimeters. Quality control includes rim impact testing, water absorption measurement, and glaze uniformity inspection.

Excavator and Bulldozer Tooth

Excavator and bulldozer teeth are made of wear-resistant alloy steel with a surface hardness of 50-55 HRC, ensuring long service life under heavy-duty conditions. The weight of the tooth varies between 15 and 35 kg depending on the model, with a length of 400 to 600 mm. The ground contact surface is wear-resistant with a 5 mm heat-treated layer, increasing shear and compressive strength. The conical and blade-like design allows easy penetration into soil, sand, and rock, and the 30-degree mounting angle optimizes shear forces. Attachment to the bucket uses standard bolts and pins, ensuring safety and quick replacement in heavy-duty work sites.

The tooth structure includes stress-relief grooves and lateral reinforcements, providing bending resistance up to 2500 N·m. Corrosion-resistant coating and UV-resistant paint extend the part’s service life. Mounting hole spacing is 120 mm with 25 mm bolt diameter for all standard models. The ergonomic blade design and curved tip reduce fuel consumption and improve excavation efficiency. These features ensure optimal performance, reduced bucket wear, and increased overall durability of heavy equipment.

ITR 110-Tooth Slewing Gear for Excavator

The ITR 110-tooth slewing gear for excavators is engineered for torque transmission and precise rotation of the cabin and boom. It is made of hardened alloy steel with tensile strength up to 1050 MPa, and the teeth are surface-hardened to 45-50 HRC for high wear and pressure resistance. The outer diameter is approximately 1,100 mm, with each tooth manufactured to tolerances below 0.02 mm for smooth, slip-free operation. The 110-tooth design ensures uniform force distribution, reducing vibration and noise during excavator operation.

The ITR slewing gear offers high fatigue resistance and can withstand dynamic loads up to 20 tons, operating in temperatures from -30°C to +80°C. The total weight is approximately 520 kilograms, and installation is performed using corrosion-resistant bolts and industrial bearings with high axial and radial load capacity. All components are manufactured according to ISO 6336 and ASTM A572 standards, ensuring durability and consistent performance of the excavator slewing system.
