A comprehensive guide to sandwich panel foam injection machines: from price to industrial applications
Did you know that the beating heart of the production line of modern and insulated sandwich panels is an advanced device? Choosing the wrong device can ruin your entire investment and productivity. Many manufacturers by searching terms like polyurethane foam injection machine second hand foam injection machine price, unwittingly expose themselves to big risks such as frequent breakdowns, low quality of the final product and lack of after-sales service. But what is the difference between a professional device and an unprincipled choice and how can you find the best option for your business? In this article, we'll take a trip into the world of foam injection machines and explore everything from performance to key buying points.
What is the sandwich panel foam injection machine and how does it work?
Sandwich panel foam injection machine is a complex industrial system whose main task is to produce an insulating core (usually made of polyurethane or PU) in the space between two metal or non-metal sheets. This process is done with extreme precision. The device pumps the two main foam materials, "polyol" and "isocyanate" from separate tanks with a precise ratio and under high pressure to the injection head (Mixer/Head). In this head, materials are mixed together at high speed and immediately injected into the empty space between two panels. The chemical reaction of these two materials leads to the expansion and creation of a hard and integrated foam with excellent thermal and sound insulation properties. Precise control of temperature, pressure and mixing ratio by advanced PLC systems ensures that the produced foam has uniform density and quality throughout the panel.
Types of polyurethane foam injection devices for sandwich panels
Foam injection machines for the production of sandwich panels are mainly divided into two general categories, each of which is designed for a different production scale:
- Continuous production line: This system is designed for mass production and factory scale. In this method, the sheets are unrolled and continuously enter the production line, and foam is continuously injected between them. High speed, uniform quality and reduction of manpower are the main advantages of these lines.
- Discontinuous production line: This method is ideal for custom productions, lower volume or panels with variable dimensions. In this system, the sheets are cut to specific dimensions and placed inside the mold or press, and then foam injection is done. Lower initial cost and high flexibility make these devices a great option for smaller workshops.
Beyond Sandwich Panels: Amazing Applications of Foam Injection Machines
Although sandwich panel production is one of the main applications of this technology, the versatility of foam injection machines has made them a key tool in other industries as well.
Cold foam injection machine for furniture and automotive industry
Cold foam, which is produced with Furniture and Bed Mattress Cold Foam Injection Machine, brings unparalleled comfort, durability and longevity to chairs and mattresses due to its open cell structure. The same technology is used in the automobile industry to produce parts such as seats, dashboards and steering wheels with a dashboard and steering wheel cover foam injection device to ensure the safety and beauty of the cabin.
Specialized applications: from refrigerator foam injection device to anti-theft door
Isolation of refrigerators and freezers plays a vital role in their energy efficiency. refrigerator foam injection machine injects polyurethane foam into the body with high precision. Also, to increase the strength and sound and thermal insulation, anti-theft door foam injection device is used to fill the inner space of these doors. Another precise application of these machines is the sealing of electrical panels with electrical panel foam injection device, which prevents the penetration of moisture and dust.
Spray foam injection device for insulation
Spray foam injection machine is a mobile and efficient solution for insulating different surfaces in the project site. This device is used for quick covering of roofs, walls, sheds and tanks and creates a seamless insulation layer.
Key points in choosing and asking the price of the foam injection machine
When making a buying decision, focusing solely on polyurethane foam injection machine second hand foam injection machine price can lead to a risky choice. A used machine or a small, non-industrial polyurethane machine may seem cheaper at first, but hidden maintenance costs, poor product quality, and production line stoppages will end up costing much more.
The table below shows a comparison between the main types of devices:
Type of machine Advantages Main application Continuous line High speed, uniform quality, mass production efficiency of large sandwich panel factories Discontinuous line Flexibility in dimensions, lower initial cost of custom production, smaller volume, workshops Spray device Irregular surface insulation, speed of execution on site, building insulation, field projects
Before buying, be sure to consider these things:
- Production capacity: The machine should be suitable for your current and future production volume.
- Parts quality: The brand and quality of pumps, injection head and PLC system directly affect the life of the machine and the quality of the final product.
- After-sales service: Ensure the existence of valid warranty, supply of spare parts and prompt technical support. Alborz Mashin Pasargad gives you this assurance by providing comprehensive after-sales service.
- Flexibility: Check the ability to adjust the density, thickness and production dimensions.

Frequently asked questions.
1- What is the main difference between low pressure and high pressure foam injection machines?
High pressure machines mix materials with very high pressure, which leads to better mixing, finer cell structure and higher foam quality. Low pressure devices have a lower initial cost and are more suitable for smaller volume productions, but they require head washing after each injection.
2- Is it recommended to buy a used foam injection machine?
No, generally it is not recommended. Second-hand devices often lack warranty, after-sales service and reliable spare parts. Also, the wear and tear of key parts such as pumps and injection heads can lead to the production of poor quality products and frequent stops in the production line.
3- What are the most important components of a polyurethane foam injection machine?
The main components include double-walled tanks for raw materials (polyol and isocyanate), high-pressure pumps with high precision, injection head (mixer), temperature and pressure control system, heated hoses and a PLC-equipped electrical panel for precise control of the whole process.https://alborzmashinpasargad.com
