Wilmington Machinery is offering a new in-line compounding option with MP800 medium pressure injection molding equipment
| Subj: Machinery
Wilmington Machinery of North Carolina LUMINA MP800–an alternative to high-pressure injection molding–is now available with a new compounding option.
With the addition of the in-line compounder to the LUMINA MP800–molders can now extrude custom formulated resins and additives and inject them directly into the part–thus reducing overall cost and improving performance. Custom formulations tend to provide the end user with reduced material costs and flexibility compared to purchasing material arriving to the plant compounded.
The in-line compounding option for the LUMINA MP800 is designed with a single 30:1 L/D screw and includes other Wilmington Machinery proprietary design/control technology. This complete system has the capabilities to process commodity and engineering grades of thermoplastic materials, including 100 percent recycled materials along with coupling agents and other fillers or additives to improve part performance properties and optimize melt flow.
The LUMINA MP800 has a large platen space to tonnage ratio. The two-stage unit has a 6 inch extruder with throughputs up to 2,000 pounds per hour, an accumulator shot capacity of 44 pounds, and an injection-pressure capability of 10,000 PSI.
The LUMINA MP800 accepts hot or cold runner molds. The hybrid design features both a hydraulic press and an electric extruder drive for energy savings, with fast cycle times exceeding all prior designs.
Since its founding in 1972, Wilmington Machinery has been building high performance, low-pressure structural foam molding machines. In addition, the company has built custom extrusion, thermoforming, and industrial blow molding machinery, along with a primary line of high capacity rotary blow molding systems for polyolefin monolayer/ multilayer barrier blow molded packaging. From a modern 65,000 SF facility in Wilmington, North Carolina, the company easily meets any customer’s need for extra-large plastics machinery. International shipments can also be arranged through the nearby deep-water Port of Wilmington.
