Machined Parts for Molded Inserts

Avanti Engineering has been in business since 1972 as a trusted industry leader in precision machined molded inserts. Avanti is a family owned business committed to producing high quality molded inserts machined to customer specifications. Molded inserts can be mass produced in quantities starting at 1,000 and are machined within tight tolerances across the entire production run. Machinists at Avanti Engineering have the experience and expert skills to manufacture molded inserts in a variety of materials. 

Molded Inserts can be produced using brass and steel. Steel is a challenging metal to machine from and to improve the machineability, 12L14 steel is used for molded inserts. This type of steel has lead added to produce parts with tight tolerances and a smooth finish for use with molded inserts. Brass is also commonly used for machining of molded inserts.  Brass is one of the easiest materials to machine and is an economical option for molded inserts.
