In today’s cost conscience and increased productivity environment, Rotational molders are continually looking for new methods to help them lower their finished goods cost in addition to overhead reduction, improved throughput and most importantly, meeting their customer’s requirements.

End users of 5 axis routers for part trimming immediately recognize the benefits of using CNC technology, one of which is the speed of use. When a double table 5 axis CNC router is applied to a large production quantity part, factory personnel who used to be tasked with just trimming the part can now be multitasked to load the untrimmed part, unload the trimmed part, perform quality assurance inspections and or additional assembly operations and in some cases, final boxing and readying for shipment without increasing the “de-mold to shipping dock” time interval

Switching the part trimming operation from the human element to a machine element reduces worker fatigue and injury, increases finished goods quality by providing an accurate and consistent trimmed product all the while reducing product scrap rates by eliminating hand trimming “slips” and handling damage.

Due to the high speed and accuracy capabilities of today’s machines, it is not uncommon to see individual part trim times reduced by 200-300% including part loading and unloading. Quintax customers are finding that locating a 5 axis CNC router within close proximity to a single or multiple rotational molding machine(s) allows them to create a “lean” work cell environment that is designed to allow for the rapid finishing of parts while reducing the material handling and transfer times often experienced when moving parts from the rotational molding machine to a dedicated trim area staffed with several employees and hand routers.

As with any capital expenditure, the same cost justification and cost benefit analysis applies to the purchase of a 5 axis CNC router, however one non-monetary metric that is consistently mentioned is the reduced personnel turnover rate associated with automated trimming operations in rotational molding facilities. Hand trimming of parts is a monotonous, repetitive process that often results in increased worker injury rates associated with cuts from hand held routers and repetitive motion injuries. As with all manual labor operations, production workers typically tire during the course of a shift which also results in injury as well as reduced productivity.

Rotational molders in today’s extremely competitive marketplace understand the use of 5 axis technology can increase their profitability, but also allows them to expand their business without large increases in human resources and floor space.

The Quintax Machining Centers product line of Ferry Industries, Inc., has been producing 3 and 5 axis CNC routers for the rotational molding industry since Ferry Industries acquired the assets of CIS of North Canton, Ohio in 1998. One of the key goals of the acquisition was to enable Ferry Industries to offer post-molding finishing capability to its rotational molding machine customers. Since the first machines rolled out of the factory in the fall of 1998, Quintax has offered a reliable, well built, economically priced router to meet the needs of the rotational molding industry.
