HTL600 Liquid Filling Machine: Complete Degassing & FDA-Certified

Filling machine piston is the core functional component of piston-type filling machines, undertaking the key tasks of liquid/paste suction, metering, and discharge in the filling process, and is widely used in piston-type filling equipment for cosmetics, food, medicine, and chemical industries, suitable for the metering and filling of medium and high viscosity products such as cream, toothpaste, sauce, and adhesive. Discus (Shenzhen) Technology Co., Ltd., a professional manufacturer of industrial filling equipment with in-depth research on core components, has developed a series of high-precision, wear-resistant, and corrosion-resistant filling machine pistons with independent intellectual property rights, which are perfectly matched with the company’s various piston-type filling machines and can also be customized for matching with third-party filling equipment. The filling machine pistons are made of high-quality materials such as food-grade 304/316 stainless steel, engineering ceramics, and PTFE composite materials, selected according to the characteristics of the filled products: stainless steel pistons are suitable for the filling of food, cosmetics, and ordinary chemical products, with excellent hygiene and corrosion resistance; engineering ceramic pistons are suitable for the filling of high-corrosion chemical liquids and abrasive pastes, with super wear resistance and chemical stability; PTFE composite pistons are suitable for the filling of high-viscosity and sticky pastes such as toothpaste and cosmetic cream, with low friction coefficient and no adhesion to materials. The piston adopts a precision CNC machining process, with a machining precision of up to 0.001mm, ensuring the perfect fit between the piston and the cylinder barrel, no liquid leakage during the filling process, and the metering precision is controlled within ±0.5%, meeting the high-precision filling requirements of various products. The piston rod is designed with a hard chrome plating process, which improves the surface hardness and wear resistance, prolonging the service life of the piston; the piston seal adopts imported food-grade or medical-grade silicone rubber and fluororubber sealing rings, with good elasticity, high temperature resistance, and aging resistance, ensuring the sealing performance of the piston for a long time, and no pollution to the filled products. The filling machine pistons are available in a variety of specifications and models, with a diameter range of 10mm-100mm and a stroke range of 20mm-500mm, which can be matched with different types of piston-type filling machines to realize the filling of products with a volume range from a few milliliters to several liters. The piston is designed with a modular structure, easy to disassemble and replace, and the sealing ring is a standard universal part, convenient for maintenance and replacement, reducing the maintenance cost and downtime of the filling equipment. In the filling process, the piston realizes the precise control of the filling volume by adjusting the stroke, and the stroke can be adjusted manually or by a servo drive system, with stepless adjustment of the filling volume, suitable for the filling of products with different specifications. The filling machine pistons developed by the company have the characteristics of stable operation, low noise, and high efficiency, and the matching with the cylinder barrel is optimized for fluid dynamics, reducing the resistance during the piston movement and improving the filling speed and stability. In practical application scenarios, the filling machine pistons are perfectly matched with the company’s cream filling machine, paste filling machine, and toothpaste filling equipment, and are widely used in cosmetic production enterprises for the filling of facial cream and hand cream, in food enterprises for the filling of peanut butter and salad dressing, and in chemical enterprises for the filling of industrial adhesive and putty. A domestic daily chemical enterprise adopted the company’s 304 stainless steel filling machine piston for its toothpaste filling production line, realizing a filling precision of ±0.2g, a production capacity of 4000 tubes per hour, and the piston service life reached more than 8000 hours without replacement of the sealing ring. The company can customize the filling machine piston according to the customer’s specific filling machine model, product characteristics, and filling volume requirements, such as adjusting the piston diameter and stroke, selecting special materials, and optimizing the seal structure, and provide professional technical guidance on piston installation, maintenance, and replacement. With high precision, reliable quality, and perfect matching performance, the filling machine piston of Discus (Shenzhen) Technology Co., Ltd. has become an important core component to ensure the high efficiency and high precision of piston-type filling equipment, and provides strong technical support for the filling production of medium and high viscosity products in various industries.
