Processing Challenges
- Pigment Dispersion and Color Matching: Achieving consistent and thorough dispersion of pigments to ensure uniform coloration and prevent color variations in paints, inks, and coatings.
- Particle Size Control: Maintaining precise control over particle size distribution during milling processes to achieve the desired texture, finish, and performance properties in the final product.
- Viscosity Management: Managing variations in viscosity, especially in formulations with high-solid content, to maintain proper flow characteristics during processing with dispersers and mixers.
- Thixotropic Behavior: Controlling thixotropic behavior, where the material becomes less viscous under shear, to ensure proper application and prevent issues like sagging or uneven coverage.
- Degassing: Effectively managing and removing entrapped air and gases during the processing stages to prevent voids, bubbles, and surface defects in the final product.
- Reactive Formulations: Managing the challenges associated with reactive formulations, including two-part coatings or inks, to achieve proper mixing and avoid premature curing.
- Temperature Sensitivity: Addressing the impact of temperature on sensitive materials, such as resins and binders, during processing to ensure stability and performance.
- Abrasive Wear on Equipment: Addressing wear and tear on milling and mixing equipment due to abrasive materials, ensuring equipment durability and consistent performance over time.
- Scale-Up Challenges: Adapting laboratory-scale processes to larger industrial scales while maintaining precision, consistency, and efficiency in material dispersion and blending.
Recommended Processing Equipment
Schold Customer Spotlights
Handy Art
Handy Art has been a trusted Schold partner since the early 1980s. As a family owned and operated company since 1974, they manufacture non-toxic, water based paints, inks, and glues. Handy Art has expanded throughout the years to meet demand and we are honored to be their exclusive mixing equipment partner.
“We chose Schold because of the robustness of their equipment, but the service excellence and high ethics were an added bonus. We didn’t really have a maintenance department, so the amount of abuse these machines could take was essential. Schold has been a great partner and it has been exciting to see the development of their technology. We now have 6 mixers – all original, none retired to date from the early 80’s!”
-Ansel Jackson, COO
Kerley Ink
Long-time customer and industry partner, Kerley Ink is known for its major contributions to the printing trade. The Schold team met with President John Whalen to capture the partnership’s long-standing history. Our founder, George Schold, worked with John’s father to create custom mixing machinery robust enough to disperse the resin bases derived from tree sap so famously used in the Kerley product.
“We are almost entirely a Schold house with very little exception. The Schold retrofitting services have been very successful, and the VFD technology is so quiet, you can have a conversation next to the machine at full power. Our oldest machine is from the Kennedy era… it’s been running strong ever since I was five years old!”
