Dispensing equipment for glass glazing is a significant investment. To achieve proper curing and reliable performance, two-component silicones must be mixed at the correct ratio and dispensed consistently. Not every dispensing system is best suited for the same application, production requirements, or working environment, so it is important to find a system that is compatible with your needs.
Our dispensing team reviews the HG 437 Big Bear and takes a closer look at its benefits and limitations to help you determine if it is the right fit for your operation.
HG Big Bear Product Details
The HG Big Bear, also called the HG 437, is a two-component dispensing system primarily used for glass glazing applications, including curtain wall and insulated glass production. Able to dispense up to 2.75 gallons per minute, the HG Big Bear is designed for high-volume production.
The system dispenses directly from 55-gallon drums and 5-gallon pails for ease of use. While it is a fixed-ratio system, the HG Big Bear dispenser can be configured for numerous material ratios, such as 2:1, 4:1, 10:1, or 12:1. It has an all-pneumatic operation, a simple design, and is mounted on wheels for easier mobility around the production floor.
Advantages
For manufacturers in search of a dispensing system for their glass glazing production floor, the HG Big Bear has beneficial features that support efficient and consistent operation.
High-Volume Capacity
One of the biggest advantages of the HG Big Bear is its high-volume capacity, which makes it well-suited for large-scale production operations. It dispenses directly from 55-gallon drums and 5-gallon pails and has an output of up to 2.75 gallons per minute.
Simplicity
The all-pneumatic system and simple design make the HG Big Bear silicone dispensing system easy to operate. Without complicated electronic controls, your team may also avoid complex maintenance issues.
Durability
The HG Big Bear is built to withstand demanding production environments. Its rugged design supports reliable performance despite rough handling. The system also operates without electronic components, which eliminates the need for an electrical connection on the production floor.
Configurability
The HG 437 Big Bear can be configured for a wide range of application requirements. The system operates at a fixed mix ratio but is available in most ratios, including 2:1, 4:1, 10:1, and 12:1. With hoses up to 50 feet long and an optional 20-foot boom arm, the Big Bear can also provide greater reach if needed.
Cost
For high-volume applications, the HG Big Bear can be a cost-effective alternative to comparable electronically powered dispensing systems. Its air-powered design eliminates the need for costly electronic components, which may help reduce maintenance requirements and potentially expensive repairs.
Limitations
While the HG Big Bear offers multiple advantages for manufacturers, it may not be the right choice for every glass glazing application. Before you invest in the Big Bear system, you should be aware of some of its potential limitations.
Less Suitable for Fieldwork
Due to its larger size and high-capacity design, the HG Big Bear is generally not ideal for fieldwork. While it has wheels for movement within a facility, its mobility is better suited to production floors than to remote jobsites. It is also not a practical dispenser for scaffolding or swing-stage glazing.
Limited Programmability
Because it is pneumatically powered, the HG 437 Big Bear may lack some of the advanced controls and features available in electronic dispensing systems. Its simple, user-friendly design makes it accessible to new operators, but it may not provide the level of process control, automation, or data tracking that some manufacturers desire.
When to Choose the HG Big Bear Over Other Dispensers
With its high output capacity, rugged construction, and ability to dispense directly from drums and pails, the HG Big Bear is a practical choice for many manufacturers.
Ideal applications include:
- High-volume insulating glass production
- Window and door manufacturing
- Curtain wall assembly
- Continuous manufacturing and assembly operations
Overall, the HG Big Bear silicone dispensing system can be a simple and cost-effective solution for large-scale glass glazing assembly in factories or large production settings. If you are looking for a dispenser for field glazing or lower volume applications, you should consider the HG Little Bear silicone dispensing system.
