M.R. Mold & Engineering to highlight silicone molding expertise at NPE

M.R. MoldM.R. Mold & Engineering will demonstrate its expertise in building silicone injection molds with tight tolerances, complex geometries and flashless processing capabilities at NPE 2018. Liquid silicone rubber (LSR) moldmaking and molding has become a specialty for the company, which is based in Brea, CA. M.R. Mold & Engineering produces molds for the medical, dental, consumer product and automotive industries.

In partnership with Krauss Maffei, M.R. Mold will run a four-cavity, in-mold slitting duckbill mold featuring a four-drop cold runner system at booth W403. In-mold slitting is part of the mold automation with specific molding machine sequencing.

In Makura USA’s booths—W911 and W1103—M.R. Mold will be represented with a four-cavity mold producing a magnification lens from optically clear silicone. A single-drop cold runner system on M.R. Mold’s universal base will feature ejection that presents the part for robotic removal.

Zieger Industries (booth 5483) will demonstrate M.R. Mold’s technology with a two-cavity LSR mold for a high-beam automotive application. The exhibit will show how silicone can be molded in applications that thermoplastics are incapable of doing.

“LSR poses challenges that do not exist in the plastics industry,” commented Rick Finnie, President of M.R. Mold. “With 34 years of experience creating solutions to those challenges, we can help companies with their requirements from concept through completion to speed their product to market.”

In M.R. Mold’s own booth (W4391), R.D. Abbott will showcase the latest addition to its technical services portfolio—a Liquid Additive Manufacturing (LAM) 3D printer. The patent-pending LAM 3D printer was developed in collaboration with German RepRap GmbH, a manufacturer of 3D printers, and Dow Performance Silicones. German RepRap’s LAM platform combined with Dow Performance Silicones’ 3D printable Silastic LC 3335 LSR is potentially capable of printing functional prototypes and enabling small manufacturing trials of complex parts. Further, the material properties closely match those of molded LSR, allowing an easy transfer into injection molding processes for high-volume manufacturing.

M.R. Mold & Engineering also designs and builds molds for silicone gumstock, thermoset and thermoplastics materials.

NPE 2018 comes to the Orange County Convention Center in Orlando, FL, from May 7 to 11, 2018.
