Since 1972, JLO Metal Products, Inc. has been providing customers with high value precision extruded products and services. JLO's focus was then as it is now, forming long term partnerships and delivering cost effective outsourcing solutions for impact-extruded aluminum products, technical extrusions and deep drawn shapes.

By outsourcing with JLO your organization can focus on its core competencies, and profit from JLO's expertise and highly developed extrusion processes. The JLO team specializes in all aspects of impact-extruded aluminum components manufacturing. From the precision extrusion of OEM and custom components, to logistical support and time sensitive delivery schedules, JLO's customer centric approach provides purchasing agents, design engineers, or company representative with superior products and services.

JLO Metal Products specializes in three impact extrusion techniques: reverse, forward, and combination. These processes are capable of fabricating many different shapes and profiles, as long as they are symmetrical around the center.

The impact extrusion method forms the part from a metal slug through a confining die. The process is done cold, and completed by a single stroke, with the application of force through a punch. This causes the metal to flow around the punch and/or through an opening in the punch or die. In reverse impacting, a blank or slug of material is placed in a die cavity and struck by the punch; this forces the material to flow outward back over the punch. In forward impacting, the material flows through the orifice of a die by the forward force of the punch. The combination impacting process involves both reverse and forward impacting in one operation. All three produce specific characteristics allowing JLO to provide extrusions for a wide range of applications.

These processes are provided at JLO's state of the art facility, which is equipped with advanced impact extrusion equipment. This includes machines with ram force up to 1000 tons and stroke length of 12" with longer lengths obtainable. Possible wall thicknesses are as thin as .010", and diameters range from 0.5" to 5". These capabilities also allow for a length to diameter ratio of up to 10:1, with tolerances of ±0.005".

In addition to the basic impact extrusion process, JLO also offers a number of secondary operations like punching or drilling holes, forming necks, drawing a part to a longer length, ironing to ensure straightness, CNC turning and CNC milling. Parts produced using impact extrusion are work hardened and supplied in as formed (-F) condition unless otherwise specified. If the final product needs to be supplied in another temper such as –T6, JLO has the heat-treating capacity in house to meet that requirement.

Many specialty finishes are also available through JLO’s trusted network of outsourced service providers. Finishing options may include chromate conversion, hard coat, multi-color and splash anodizing, polishing, buffing, etching, painting or powder coating. Parts may also be branded with numbers, logos, graphics, custom messaging or bar codes.

At JLO quality is a high priority and embedded in company culture. This is backed up by ISO 9001 and TS 16949 certifications as well as full compliance with all applicable ASTM, Mil-Spec, and ITAR standards. We employ thorough testing, inspection, and QA procedures, incorporating hardness testing, visual and final inspections, CMM, and full process manual QA protocols.
