Bmc injection machine

Types of BMC injection machines

BMC injection machines are also known as bulk molding compound machines. They are used to process bulk molding compound, which is a type of composite material formed by combining thermosetting resin, filler, and reinforcement. A BMC injection machine has a few common types.

• Hydraulic BMC injection molding machine

It is an injection molding machine that uses hydraulic pressure to create a material for the desired object. The molding process is done by injecting the required material into the plastic mold. The pressure is then applied to the mold to create the custom plastic part. Hydraulic machines are typically used in high-pressure use cases. They are the oldest and most common type of injection molding machine currently in use. A hydraulic pump produces the pressure in these machines, which can be adjusted in a variety of ways. Because of the high level of precision, the hydraulic injection machine is very good at creating complex parts.

• Vertical BMC injection molding machine

Ordinary horizontal injection molding machines are placed horizontally, while vertical BMC injection molding machines are placed vertically. The injection unit of a standard horizontal injection molding machine is fixed horizontally, while the injection unit of a vertical injection molding machine is fixed vertically. Vertical machines are popular for insert molding, molding metal parts, and automotive components, among other things. In addition, vertical injection molding machines are highly adaptable for various types of insert injection molding processes and are commonly used in the automotive, medical, and electronics industries. Additionally, the vertical machine's small footprint and ease of operation make it ideal for quick tooling and material changes.

• Electric BMC injection molding machine

An electric injection molding machine is a machine that uses electric motors to drive the plasticizing screw, the mold-cooling system, and the hydraulic system. Electric injection molding machines are great for accuracy and control. This is because they have a high level of precision and control. They also have a higher repeatability. They have a high level of energy efficiency and provide a clean and quiet operation environment. They are very good for producing thin-walled products and products that have complex shapes.

• Multicolor BMC injection machine

Multicolor BMC injection machines can produce multicolor products, such as multicolor buttons, multicolor frames, and multicolor medical products. The machines use an injection unit that has more than two injection units. The units can work separately or at the same time, depending on the requirements of the product.

Specifications and maintenance of BMC injection machines

Specification

• Clamping force: The clamping force refers to the force applied to the mold by the clamping mechanism of the BMC injection molding machine. The BMC injection machine often has a clamping force ranging from 1000 kN to 10,000 kN, depending on the size and requirements of the BMC parts.
• Injection capacity: The injection capacity of the BMC injection machine indicates how much BMC material the machine can inject into the mold. This is often measured in kilograms, which can range from a few kilograms to several hundred kilograms, depending on the application needs.
• Injection pressure: Injection pressure is the pressure at which the BMC material is injected into the mold cavity by the injection unit of the machine. BMC injection machines typically have injection pressure ratings ranging from 1000 bars to 3000 bars, or even more.
• Temperature control: BMC injection machines are equipped with advanced temperature control systems to precisely regulate and maintain the temperature of the barrel, nozzle, and mold. The temperature ranges for BMC injection molding are as follows: the temperature of the plasticizing unit is typically between 200°C and 280°C, the temperature of the mold is between 130°C and 200°C, and the temperature of the cooling water is usually between 10°C and 20°C.

Maintenance

• Regular inspection: Regularly inspect the overall condition of the BMC injection machine, including the hydraulic system, electrical system, and safety devices. It's important to check for any leaks, loose connections, or abnormal noises and address them promptly.
• Lubrication: Proper lubrication is a critical part of maintaining a BMC injection machine. Operators should regularly lubricate the moving parts of the machine, such as the clamping mechanism and injection unit, with the recommended lubricants. It helps to minimize friction and wear and ensure smooth operation.
• Cleaning: Regularly cleaning the BMC injection machine is also crucial. Keep the working area of the machine clean and free of debris. It's also important to clean the injection unit and hopper to prevent material contamination during color changes or tooling changes.
• Maintain temperature: Maintaining proper operating temperatures is essential for BMC injection. It's important to ensure that the temperature control systems of the machine are functioning correctly. Regularly calibrate and adjust the temperature controllers to keep the temperature within the desired range.
• Safety protection: Finally, safety is paramount. Operators should pay close attention to safety precautions when using a BMC injection machine. It's important to strictly follow the operating procedures and wear the necessary protective equipment to ensure safety during operation.
