4 Types of Industrial Machines Used in the Plastics Industry

The plastics industry is growing at a fast pace; thus, the industrial machines used in this industry play a significant role in its development. Production efficiency has been considerably boosted by employing these machines for plastic production. They help reduce costs, enhance productivity, and elevate the quality of the product.

4 Types of Industrial Machines Used in the Plastics Industry
Many machines are employed in the plastic industry, and this article lists the machine types and their uses.

Plastic machinery – An overview
Plastic machinery is the standard term used for several devices and machines in the plastic processing industry. When considering the production process, plastic machinery is categorized into four types: plastic molding machinery, plastic processing auxiliary machinery, plastic secondary processing machinery, and plastic compounding machinery.

Some other industrial machines used in the various stages of plastic processing and manufacturing are injection molding machines, film-blowing machines, vacuum forming, rotational molding, granulators, and shredders. CNC routers also play an essential role in the plastic trimming processes and the engraving and cutting of sheets of some materials.

Types of machines used in the plastic industry
Various machines utilized in the plastic industry for quality output are detailed below:

1. Laser cutting machine
Does one know which machine is used for designing and precision cutting in the plastic industry? The laser-cutting machine plays the primary role in this process. This machine works on the CNC (computer numerical control) and laser optics settings. These settings help control and manage the intensity of the laser beam and bring the design effect needed for the manufacturing process. The CNC is programmed with CAD software (Computer Aided Design), which directs it to perform the cutting, etching, or engraving required for the laser cutting project. The spick and span cuts are produced by the high-powered laser beam emitted by this machine. The laser cutting machine is used for engraving designs or precision cutting on materials like plastic and wood. It primarily finds its application in industrial manufacturing.

This machine is also used for the precision cutting of machine components in engineering, cutting flat sheet material like metal, and cutting piping and structural material. It can be used for smaller and larger industrial projects based on capacity and size.

2. Capsule-filling machine
The capsule-filling machine, also known as the capsule filler, is used in the pharmaceutical industry to fill empty capsules. These capsules consist of pharmaceutical ingredients. As per their functions and uses, these machines are classified into two primary categories: professional and personal capsule-filling. The personal machine is used on a small scale to fill the capsules with the ingredients. At the same time, professional machines are the automatic machines used for large-scale production. The capsule-filling machine fills the translucent and colorless capsules in the capsule-filling tray. Then, the capsule caps are removed from the capsule body to fill it with the prescribed ingredients. Afterward, capsule caps are rearranged, and the filled capsules are ejected from the machine. This industrial machine comes in automatic, semi-automatic, manual, or hand-operated forms.

3. Blow molding machine
Blow molding is the method that is used to manufacture hollow thermoplastic products like hollow containers and tube films. The blow molding machine is also called hollow blow molding. The plastic is molded into specific shapes by blowing air into the mold cavity. This machine is divided into three types: extrusion, injection, and special structure. The main components of these industrial machines are the head, extruder, clamping system, hydraulic system, pneumatic system, electric control system, and automatic clip parts. These high-efficiency machines are user-friendly and have high performance. This machine has various applications, ranging from producing products like multilayer composite films to polyolefin hollow containers. These containers are used in the cosmetic and food industries.

4. PVC extrusion machine
These industrial machines perform the transformation process. The plastics industry primarily uses the PVC extrusion machine to produce or manufacture solid products. Not all extruder machines have a single cylinder. Some come with a double cylinder, which is valuable for extruding delicate materials such as PVC. These machines can also produce composites of several materials and mixtures. Plastic extruders are used in sheet, profile, and pipe extrusion applications to shape plastic materials.

Analyzing extruder screws, barrels, and tips is necessary when choosing extrusion equipment. High-carbon, high-chrome, and unique tool steels are examples of screw materials. For extruder screws, nitriding, carbide coating, and chrome plating are typical surface treatments. Tool steels are also used to make extruder barrels but frequently have liners that withstand wear and corrosion.

Plastic is widely used all across the globe in daily life. The plastic industry today has a significant position globally. The production of plastic products has also increased due to their high utility and advantages. Due to this, industrial machines for plastics have also been gaining great significance. These machines must be well maintained and perfectly working for the quality production of plastic products or semi-products. It could save time and effort and produce premium-quality output.
