Hansheng Automation machines precision parts for filling equipment, working from customer drawings for one-off and small-batch orders. A filling machine usually has five hardware systems: drive, filling, pneumatic control, electrical control, and external equipment. Each system has a defined job. The parts inside them must match in size, material, and heat treatment for the line to run well.
Drive system
The drive system contains the motor, pulleys, the worm shaft of the reducer, and gears. The motor provides power. Pulleys and gears transmit torque. The worm shaft lowers speed and raises torque. This keeps the filling section, capping head, and indexing wheels moving together and sets the filling rhythm. Common parts include worm shafts, gears, pulleys, bushings, and connecting flanges. Material choice follows load and wear: 45# steel, 42CrMo, 304 stainless steel, 316 stainless steel, or aluminum. Heat treatment and surface treatment may include quenching and tempering, black oxide, nickel plating, and anodizing. Fits usually hold between ±0.01 mm and ±0.05 mm unless the drawing calls for something else.
Filling system
The filling system contains the filling cylinder, filling valve, and metering cylinder. The cylinder drives the piston. The piston draws and pushes product. A check valve controls flow direction. The metering cylinder measures the volume for each fill. This system determines fill accuracy and consistency. Valve cores, valve seats, metering pistons, piston rods, and seal glands often need machining to drawing. Material and surface finish follow product corrosion, viscosity, and cleaning needs. Stainless valve cores often get grinding and polishing. Aluminum parts may get anodizing. Customer drawings can specify non-standard ports and mounting dimensions.
Pneumatic control system
The pneumatic control system contains cylinders, solenoid valves, and the pneumatic control box. Cylinders extend and retract. Solenoid valves switch air on and off. The control box manages the pneumatic components. The system responds quickly and holds position well, which suits frequent starts, stops, and positioning in filling. Parts include cylinder end caps, pistons, valve bodies, connecting blocks, mounting plates, and air fittings. Sealing and alignment matter, so the process controls bore and shaft fits, face flatness, and surface roughness. Hard anodizing, nickel plating, and black oxide are common choices.
Electrical control system
The electrical control system contains a microcomputer programmer and an electrical control box. It handles start, stop, speed adjustment, and fault alarms. It coordinates the actuators through signal input and program logic. Metal parts for the control box include mounting plates, panels, heat sink brackets, sensor brackets, and rail connectors. Sheet metal bending, hole position, interchangeability, and surface treatment consistency all affect assembly.
External equipment
External equipment includes the cap sorting motor and cap placement device, the cap pressing cylinder, and the cap pressing device. The motor drives the sorting mechanism. The placement device puts caps in position. The cylinder and pressing device complete the press. These units support the rest of the filling process and reduce manual work. Parts such as motor mounts, guide pieces, cylinder connectors, pressing wheels, dies, indexing wheels, and star wheels often need machining. Machinists make dies, pressing wheels, and similar key components for packaging machinery to customer drawings.
A filling machine has several subsystems that work together. Drive, filling, pneumatic, electrical, and external equipment each have clear functions. The size, material, and heat treatment of a critical part can affect the whole line.
