Types of benchtop injection molding machines

There are two primary types of benchtop injection molding machines based on their method of operation.

• Hydraulic benchtop injection molding machines: Hydraulic machines use fluid power to operate the injection unit, clamping system, and other functional parts. They rely on hydraulic pressure generated by a pump to move the piston within the cylinder, which injects melted plastic into the mold cavities. Hydraulic machines are known for their strength, versatility, and ability to handle a wide range of materials and mold sizes. They can accommodate complex molds and produce intricate parts with varying degrees of complexity. Hydraulic machines have been the traditional workhorses of the injection molding industry for decades. They excel at high production volumes where speed and efficiency are paramount. Benchtop hydraulic injection molding machines generally cost less than their electric counterparts.
• Electric benchtop injection molding machines: Electric molding machines utilize servo motors and other electric components to provide precise control over the injection process. The role of the motor in the machine is to inject the melted plastic into the mold cavity. Electric machines offer improved energy efficiency, higher production speeds, and lower noise levels compared to hydraulic machines. These machines excel at producing high-precision parts with tight tolerances. Benchtop electric injection molding machines usually have a higher production rate because of their rapid cycle time. The increased automation and remote monitoring of the process also reduce the need for constant operator supervision.

Specification and maintenance of benchtop injection molding machines

• Machine Size and Clamping Force: The machine's size will determine the size of the worktable. The clamping force, measured in tons, indicates the amount of force the injection unit can exert to hold the mold closed during the injection process. For reference, a machine with a clamping force of between 5 and 20 tons is adequate for small parts like bottle caps.
• Injection Volume and Pressure: The injection volume tells how much plastic can be injected in one go. It gives an idea of the part size the machine can make. The injection pressure indicates the force at which plastic is injected into the mold. A machine with a maximum pressure of 8,000 to 20,000 psi is suitable for small to medium-sized parts.
• Power Requirements: Benchtop molding machines usually require single-phase power between 220 and 460 volts, depending on the machine size.
• Mold Compatibility: Most benchtop machines use Standard T-slot molds. The maximum mold size is usually about 12 x 12 inches.
• Control System: Machines have an electronic or PLC control system with a touchscreen interface. Users can set the injection speed, temperature and other process parameters from this user-friendly interface.
• Safety Features: Safety features include emergency stop buttons, safety doors and interlocking systems that prevent access to the mold area when the machine is running.

To keep benchtop injection machines working great, routine upkeep is key. Regular servicing checks of vital machine parts, including the injection units and the hydraulic systems, are also essential. Operators should clean molds and the hopper daily after use to stop any build-up of old plastic from clogging the system or affecting product quality. They should also inspect all wear and tear on vital moving machine parts like rails, screws, and injection units, then quickly replace worn-out parts. Conducting periodic calibrations of temperature and pressure settings is crucial for consistent product quality. During use or repair, always follow the manufacturer's safety advice and feature guidelines.
