Tooling has been a valuable resource in the fabrication and metalworking industry since the advent of powered and special-purpose machines during the industrial revolution. Tooling is a general term used to refer to items that cut, shape, and form metals or other materials. Tooling types vary widely and perform a wide range of functions depending on the metal part or component being manufactured.

High-quality tooling is crucial to the success of the fabrication process. Despite the initial investment, proper tooling facilitates the manufacture of durable goods, making an it an essential cost. In addition to superior product quality, high-quality tooling allows manufacturers to significantly increase production quantities with enhanced precision and repeatable accuracy—and the larger the production run, the more the tooling cost is mitigated. Mass production also facilitates the bulk purchase of materials, resulting in substantially lower material and labor costs.

Every cutting, bending & forming component inside Keats tooling is inserted for quick changeovers and ease of maintenance.  We use only the highest quality tool steels for every station in every die.  Keats also standardizes all tooling with SMED (Single Minute Exchange of Dies) in mind to ensure that setup times are short & tooling clamps quickly to its designated production machine.

Other essential protective measures, such as proximity sensors, which detect the distance of the tooling from various surfaces to help reduce the risk of crashes, heavy impacts, and damage due to equipment malfunction.

Purpose: This study evaluated the in vivo response of promoting new bone growth and bone apposition with NanoMetalene (NM) compared with PEEK alone in a cancellous implantation site with an empty aperture.

Protective measures for tooling guarantee long tooling life as well as manufacturing precision and accuracy. Quality assurance is essential in numerous fabrication methods and tooling types including:

Methods: Implants and funding for this study were provided by SeaSpine (60,000 USD). Cylindrical dowels with two apertures were prepared as PEEK with a sub-micron layer of the titanium (NM). The titanium coating was applied over the entire implant (Group 1) or just the apertures (Group 2). Polyether ether ketone implants with no coating served as controls (Group 3). Implants were placed in the cancellous bone of the distal femur or proximal tibia with no graft material placed in the apertures in eight adult sheep. Bone ongrowth to the surface of the implant and ingrowth into the apertures was assessed at 4 and 8 weeks after surgery with micro-computed tomography (CT) and undecalcified histology.

High-quality tooling is usually equipped with several protection measures to ensure the longevity of the equipment. Load tonnage monitors help protect the tooling and dies from excessive impact forces, overloading, and other associated damage. They can also simplify tooling setup since planning for a known tonnage results in fewer equipment adjustments. Load tonnage monitors allow manufacturers to produce quality parts with the least amount of tonnage, thus reducing wear and tear on the tooling equipment.

Our detailed and comprehensive tooling development systems and procedures are designed to produce optimal results while being flexible enough to accommodate any tooling design requirement. The design process, from concept to completion, may consist of as many as 40 steps depending on the tooling application. This thorough process ensures that we create efficient tooling in advance of production, mitigating any cost risk associated with tooling redesign during the production run.

Results: The apertures in the implants were notably empty in the PEEK group at 4 and 8 weeks. In contrast, new bone formation into the apertures was found in samples coated with NM even though no graft material was placed into the defect. The bone growing into the aperture tracked along the titanium layer. Apertures with the titanium coating demonstrated significantly more bone by micro-CT qualitative grading compared with PEEK with average bone coverage scores of Group 1 (NM) 1.62±0.89, Group 2 (NM apertures only) 1.62±0.77, and Group 3 (PEEK) 0.43±0.51, respectively, at 4 weeks (p<.01) and Group 1 (NM) 1.79±1.19, Group 2 (NM apertures only) 1.98±1.18, and Group 3 (PEEK) 0.69±0.87, respectively, at 8 weeks (p<.05). The amount of bone in the apertures (ingrowth) quantified using the volumetric data from the micro-CT supported an overall increase in bone volume inside the apertures with the titanium coating compared with PEEK. Histology showed newly formed woven bone tracked along the surface of the titanium in the apertures. The PEEK interface presented the typical nonreactive fibrous tissue inside the apertures at 4 weeks and some focal contact with bone on the outside at 4 weeks and 8 weeks.

Conclusions: Micro-CT and histology demonstrated bone ongrowth to the surfaces coated with NM where the newly formed bone tracked along the thin titanium-coated surfaces. Polyether ether ketone surfaces presented the nonreactive fibrous tissue at the interface as previously reported in preclinical scenarios.
