Our total commitment to our client’s goals means rapid response times, cost-efficient processes and cost reduction opportunities and seamless JIT delivery. Stern Manufacturing utilizes the industry gold standard ERP software system, IQMS, to coordinate every phase of production.


Custom Milled Compounds

Stern Manufacturing is one of the few custom rubber molders that also custom mixes its own rubber compounds. Most rubber molders need to order their compounds from custom mixers. This critical competitive advantage provides numerous benefits to our clients. Stern Manufacturing tailors each formulation batch to the specific requirements of the part. Chemical resistance, abrasion resistance, UV resistance, tensile strength, aging, elongation, viscosity, durometer and other characteristics can be specially calibrated to stringent requirements.
