Plastic injection moulding machine with packaging

Types of plastic injection moulding machine with packaging

A plastic injection moulding machine with packaging involves heating up the plastic until it is in a molten form, injecting it into a cold cavity to form solid shapes, and cooling it down before removing it. Different types of such machines exist, each with distinct mechanisms and benefits.

• Direct Injection Moulding Machines

  Direct injection moulding machines, also known as injection machines, work by injecting the molten plastic directly into a mould to create specific shapes and forms. The injection process begins with the heating of plastic granules in an injection unit until they become molten. A screw then pushes the molten plastic through a nozzle into a pre-heated mould. The plastic cools and solidifies in the mould, taking its shape before the mould opens, and the finished product is ejected.

• Insert Injection Moulding Machines

  Insert injection moulding machines are used to make parts with embedded components, such as metal inserts or electronics. These machines first inject molten plastic into a mould. Before the plastic cools and solidifies, the embedded component or insert is added, and the rest of the plastic is then injected to fully encapsulate the insert. Metal inserts are usually pre-heated to reduce the cooling time in the mould. The machine then electrically or ultrasonically bonds the plastic to the insert, creating a secure and functional part.

• Strayless Injection Moulding Machines

  Strayless injection moulding machines offer an efficient way to produce large quantities of parts with consistent quality and low production costs. They work by injecting plastic into a mould to create complex shapes in one quick and simple step. The process is repeatable and highly automated, making it easy to scale up production while maintaining high precision and accuracy. Strayless injection moulding machines are ideal for making parts with intricate geometries or features that are difficult to achieve using other methods.

• Multi-material Injection Moulding Machines

  Multi-material injection moulding machines combine two or more materials in a single part. This process offers unique material properties, visual effects, and design possibilities that are unattainable with traditional moulding techniques. Machines that use multi-material injection to create parts usually have separate feed systems for each material used. The different materials are then injected into a common mould where they fuse together to form a new shape. Alternatively, they can be layered or overmoulded on each other. Multi-material injection allows for the production of lightweight components with complex structures and multiple functions that can replace assemblies made from several different pieces. It also makes it possible to combine materials with dissimilar characteristics such as rigidity, transparency, and flame resistance.

Specification & Maintenance

The plastic injection machine specs vary according to the model, make, and intended use. Below are the general specs that business buyers can expect.

• Clamping Force: The force used to hold the injection mold in place as molten plastic material fills the latter is known as clamping force. Injection molding machines possess clamping force ranging from as low as 1 ton to as high as 5,000 tons.
• Shot Capacity: Shot capacity refers to the volume of plastic material an injection molding machine can inject in a single cycle. The shot capacity of plastic injection molding machines ranges from less than an ounce to more than 1 ounce.
• Machine Dimensions: The detailed dimensions of plastic injection molding machines varies depending on the type and model. Generally, horizontal machines are taller and wider than vertical machines, which are often more compact.
• Machine Weight: Plastic injection machines can weigh up to 100 tons, depending on whether it is a vertical or horizontal machine. Generally, horizontal injection molding machines are heavier than vertical molding machines because of the heavier parts required to move the material.

Maintenance

For longevity and better performance, it is crucial to maintain the plastic injection molding machine. The following maintenance tips can help business buyers keep their machines in the best shape.

• It is necessary to perform routine lubrication. Injecting grease at the right places helps minimize wear and tear, keep the parts moving smoothly, and reduce the noise produced by the machine.
• Frequent cleaning is vital to keep molding machines in the best condition. When cleaning, focus on getting rid of any dirt or residue left after the injection of molding materials. Use degreasing agents to deal with any grease and lubricating residue.
• Regular inspection helps identify any parts that may need replacement or repair. Taking action promptly helps prevent costly downtime and damages to products.
• Employ cooling systems as recommended by the manufacturers. This helps prevent overheating and maintains the temperature of the molds and materials consistent during the injection molding process.

Scenarios in which a plastic injection moulding machine with packaging can be used

The plastic injection moulding machine with packaging is a versatile tool that can be used in various industries to meet different packaging needs. Here are some of the scenarios in which the machine is commonly used.

• Food packaging

One of the most common uses of the moulding machine is in the food industry to make containers, cups, trays, and other packaging components required. The packaging created is usually suitable for appliances such as microwaves and ovens.

• Consumer goods packaging

The machine can be used to create packaging for a variety of consumer goods. This includes products like bottles, jars, blisters, clamshells, and sorting trays. These are usually made from rigid or lightweight materials for ease of use and portability.

Automotive parts can be made through injection moulding. This includes items like instrument panels, air ducting, door trims, and other components that are usually made of lightweight materials. These have good durability and are low maintenance.

• Medical device packaging

Injection moulding machines with special packaging are used to create precise, sterile packaging for medical devices. The devices are usually made with high levels of precision control to meet the industry's stringent standards, in addition to incorporating features that allow for easy sterilization and security.

Moreover, some machines can be used together with smart manufacturing technologies to create individualized packaging solutions for medical products.

How to choose plastic injection moulding machine with packaging

Generally, deciding on a suitable injection moulding machine may be very tough for business buyers. It is essential to take several important requirements into deep consideration.

• Production scale and capacity

  Business buyers need to consider the required production scale and capacity. This means that they need to think about the planned output, frequency of use, and so on. Based on these factors, buyers can decide on the clamping force and injection volume of the injection moulding machine to meet production needs.

• Industrial applicability

  Industrial applicability is also an important factor in deciding on a suitable injection moulding machine. Business buyers need to consider the specific industry and product type, working environments, and other aspects. These factors may directly influence the choice of injection moulding machine types and specifications.

• Machine quality and reliability

  The quality and reliability of the injection moulding machine are extremely important for business buyers. They need to ensure that the selected machines have stable performances and possess good reliability. This can reduce the risk of breakdown to ensure smooth operation of production lines.

• Integration and automation

  Modern industrial productions require a high level of automation. Hence, business buyers need to consider the integration and automation of the injection moulding machine. They need to ensure that the selected machines possess functions of automation like automatic feeding, temperature control, and robot joint operations. These help to enhance production efficiencies and reduce manual operations.

• Costs

  At last, business buyers need to take both the upfront costs and long-term operating costs into account. In addition to the purchasing costs of the injection moulding machines, the operating energy consumption, maintenance needs, and accessory replacement expenses also need to be considered.
