For many years, 3D printing technology — or additive manufacturing, as it is often called — has been gaining ground against long-established manufacturing processes. In the early days, additive manufacturing was relegated to the realm of prototyping.
A lot has changed in just 35 years. Consider how modern industrial ovens compare with those of the past. The innovations help improve the thermal processing of your products.
When I started my junior year of engineering school in the mid ’80s, the lease on the apartment I rented did not start until October. The university was 200 miles from where I grew up, but it just happened that my dad was working at that time in the same city.
If an application generates heavy amounts of moisture or involves drying solvents, the role of proper ventilation and the design of the exhaust system must be considered.
Drying applications vary: from drying frac sand — a relatively simply process often performed for screening purposes — to applications like drying wetted primer in ammunition — a process that depends on accurate temperatures sustained over time. Yet, in drying applications from simple to complex, airflow and temperature uniformity makes a difference.
Thermally curing adhesive bonds remains an essential part of medical-device manufacturing because thermal curing provides a high degree of process repeatability.
Seeking to develop a two-part polymer adhesive bonding step in their assembly process, a medical-device manufacturer in the northern United States performed extensive design of experiments (DOE) with multiple variables.
