The challenge was to meet the need to produce these parts at such a high volume and generate a print that would match the specified dimensions. The goal was to meet the customer’s unique standards at a targeted price based on their high volume order of 100k custom hubs per month. **What Hartford provided** Hartford Technologies researched similar caps and hypodermic needles to approximate the required dimensions for the hub. Design prints were created and approved. The parts were then prototyped on the CNC machines, allowing collaboration with the medical manufacturer to refine the new product prototype through to production. A coil-fed Escomatic machine was used in the process. These machines are required to give the ability to produce parts in high volume with short cycle times while still maintaining the required quality. The connector hub for the hypodermic needle was made out of aluminum. The requirements for the finish of the part (being smooth with no nicks or tool marks) were much more strict than what is produced for other industries. Tolerances are also much tighter causing advanced inspection techniques. As a result, the production timing was adapted significantly to deliver the quality required.  **The Result** Approximately 1 million custom hubs were ordered–at a production rate of 100k components per month–in order to meet the customer’s target pricing requirements successfully.   [![Request a Quote](https://no-cache.hubspot.com/cta/default/2564859/f9333cfd-c5dd-4ab6-86af-8298ec133e38.png)](https://cta-redirect.hubspot.com/cta/redirect/2564859/f9333cfd-c5dd-4ab6-86af-8298ec133e38)   [![Hartford Technologies Rocky Hill, Connecticut](https://resources.hartfordtechnologies.com/hs-fs/hubfs/header-logo-5.png?width=216&height=29&name=header-logo-5.png)](https://hartfordtechnologies.com/) 1022 Elm Street - Rocky Hill Connecticut 06067 - Tel: 860-571-3602 - Fax: 860-571-3604x #### CUSTOM BEARING ASSEMBLIES - [Special Bearings](https://hartfordtechnologies.com/custom-bearing-assemblies/special-bearings/) - [Cage Bearings](https://hartfordtechnologies.com/custom-bearing-assemblies/cage-bearings/) - [Needle Bearings](https://hartfordtechnologies.com/custom-bearing-assemblies/needle-bearings/) - [Drawn Cup Needle Bearings](https://hartfordtechnologies.com/custom-bearing-assemblies/drawn-cup-needle-bearings/) - [Cage Needle Bearings](https://hartfordtechnologies.com/custom-bearing-assemblies/cage-needle-bearings/) - [Thrust Bearings](https://hartfordtechnologies.com/custom-bearing-assemblies/thrust-bearings/) - [Plastic Bearings](https://hartfordtechnologies.com/custom-bearing-assemblies/plastic-bearings/) - [Ball & Roller Retainer Assemblies](https://hartfordtechnologies.com/custom-bearing-assemblies/ball-roller-retainer-assemblies/) - [Ball Sleeves](https://hartfordtechnologies.com/custom-bearing-assemblies/ball-sleeves/) - [FAQ – Custom Bearing Assemblies](https://hartfordtechnologies.com/custom-bearing-assemblies/faq-custom-bearing-assemblies/) #### Precision balls - [Chrome Steel Balls](https://hartfordtechnologies.com/precision-balls/chrome-steel-balls/) - [Stainless Steel Balls](https://hartfordtechnologies.com/precision-balls/stainless-steel-balls/) - [Carbon Steel Balls](https://hartfordtechnologies.com/precision-balls/carbon-steel-balls/) - [Brass Balls](https://hartfordtechnologies.com/precision-balls/brass-balls/) - [Tungsten Carbide Balls](https://hartfordtechnologies.com/precision-balls/tungsten-carbide-balls/) - [Precision Glass Balls](https://hartfordtechnologies.com/precision-balls/precision-glass-balls/) - [Plastic Balls](https://hartfordtechnologies.com/precision-balls/industrial-plastic-balls/) - [Small Ball Pack Program](https://hartfordtechnologies.com/precision-balls/small-ball-pack-program/) - [FAQ - Precision Metal Balls](https://hartfordtechnologies.com/precision-balls/faq-precision-metal-balls/) #### Custom Bearing Components - [Custom Roller Bearings](https://hartfordtechnologies.com/custom-bearing-components/roller-ball-bearings/) - [Needle Bearing Retainers](https://hartfordtechnologies.com/bearing-parts/needle-bearing-retainers/) - [Bearing Sleeve / Wear Sleeve](https://hartfordtechnologies.com/bearing-parts/bearing-sleeve-wear-sleeve/) - [Tripot / Tripod Ball – CV Joint](https://hartfordtechnologies.com/bearing-parts/tripot-cv-joint-trunnion/) - [Bearing Races](https://hartfordtechnologies.com/bearing-parts/bearing-races/) - [Bearing Cages / Seperators](https://hartfordtechnologies.com/custom-bearing-components/bearing-cages/) - [FAQ - Bearing Parts](https://hartfordtechnologies.com/bearing-parts/faq-bearing-parts/) #### Custom Precision Pins - [Precision Pins & Shafts](https://hartfordtechnologies.com/custom-precision-pins/pins-and-shafts/) - [Needle Rollers](https://hartfordtechnologies.com/precision-pins-rollers/needle-rollers/) - [Precision Rollers](https://hartfordtechnologies.com/precision-pins-rollers/precision-rollers/) - [Special End Rollers Steam](https://hartfordtechnologies.com/precision-pins-rollers/special-end-rollers-steam/) - [Tapered Rollers](https://hartfordtechnologies.com/precision-pins-rollers/tapered-rollers/) - [Pivot Pins](https://hartfordtechnologies.com/precision-pins-rollers/pivot-pins/) - [Dowel Pins](https://hartfordtechnologies.com/precision-pins-rollers/dowel-pins/) - [Knurled Pins](https://hartfordtechnologies.com/precision-pins-rollers/knurled-pins/) - [FAQ - Precision Pins & Rollers](https://hartfordtechnologies.com/precision-pins-rollers/faq-precision-pins-rollers/) - [About Us](https://hartfordtechnologies.com/about-us/) - [Contact Us](https://hartfordtechnologies.com/contact-us/) - [Global Team](https://hartfordtechnologies.com/global-team/) - [Resources](https://hartfordtechnologies.com/resources/) - [Privacy Center](https://hartfordtechnologies.com/privacy-center/) - [Privacy Policy](https://hartfordtechnologies.com/privacy-policy/) - [Terms and Conditions](https://hartfordtechnologies.com/standard-terms-and-conditions-of-sale/) © Copyright 2024.
