Improving Manufacturing for Medical Equipment Used in Cardiac Treatments

The medical technology industry is a rapidly expanding one, but unlike other industries growing just as quickly, medical equipment has unmatched demand for precision, reliability, and safety. Because the quality of medical equipment directly affects the health and wellbeing of patients, including those who are unable to speak for themselves (such as children and the elderly), the medical industry has to meet a standard of ethical production and testing practices. At MultiSource Manufacturing LLC, we are dedicated to providing unparalleled quality for components and assemblies used to fabricate medical equipment that is distributed globally. Our goal is to continually improve our practices and products for all areas of the medical industry we provide for, including cardiac medicine and treatments.

 

A large portion of the components and assemblies we manufacture are utilized in the cardiology branch of medicine for cardiac treatments ranging from minor to aggressive heart issues. The medical equipment we fabricate on our state-of-the-art production floor is used in various treatments, including:

 

Atrial Fibrillation: This cardiac affliction manifests as an irregular heartbeat caused by the upper chambers of the heart beating rapidly and out of sync with the lower chambers. This increases the risk of a stroke or heart attack. The components we manufacture are used in the equipment that produces medications or catheterization systems that treat atrial fibrillation.

 

Cardiac Ablation: This is a primary treatment for atrial fibrillation and other causes of an irregular heartbeat when medications fail. Using a catheter system, surgery, or a combination of both, surgeons can create scar tissue in specific areas of a patient’s heart. This scarring alters the rhythm of the heartbeat, stabilizing and syncing the chambers. Our components are used in many various types of ablation equipment.

 

Implantable Devices: Our components are used in the fabrication of ICDs (implantable cardioverter defibrillators), one of the most commonly used implantable devices in the United States. Additionally, we manufacture equipment used in other implantable devices, including pacemakers and coronary stents, for treating cardiac health issues.

 

Catheterization: Cardiac catheterization can be used to test for heart conditions or treat an existing condition. The long, thin tubing inserted into arteries, heart blood vessels, or veins allows blood flow to and from the heart when that flow would otherwise be unreliable. We manufacture several components used in cardiac and other catheterization systems.

 

Surgical Navigation: In many surgical operations, including almost all cardiac and open-heart surgeries, highly advanced navigation systems are critical. These navigation systems require extreme precision and trusted performance because they introduce another factor into the human body during surgery. The components we fabricate for surgical navigation devices are highly accurate and well-engineered products.

When you work with MultiSource, you gain the benefits of a state-of-the-art prototyping program that promises quality from the very beginning. Our prototyping technicians utilize additive manufacturing technologies to build unique components and assemblies for a broad range of industrial applications.

 

Additive manufacturing today is synonymous with 3D printing, and while it’s a newer industrial process, it has a rich, albeit short, history starting in 1974.

 

Additive Manufacturing Timeline

 

1974:  David E. H. Jones published a conceptual overview of 3D printing in his column in the New Scientist journal.

 

1981: After the development of early additive manufacturing technologies in 1980, Hideo Kodama, working at the Nagoya Municipal Industrial Research Institute, created two ways of additive manufacturing with a thermoset polymer.

 

1984: The stereolithography process was developed and patented by Olivier de Witte, Alain Le Méhauté, and Jean Claude André. Soon after, Chuck Hull from 3D Systems Corporation patented his own stereolithography fabrication system that used ultraviolet light lasers to cure photopolymer layers.

 

1988: Fuel deposition modeling (FDM), the type of 3D printing used by most commercial consumers, was developed by S. Scott Crump. His well-known company, Stratasys, marketed the first commercial FDM machine in 1992.

 

1995: The Fraunhofer Institute introduced selective laser melting processes.

 

2009: Any original patents for FDM machines and the FDM printing process expired. Because the industry was now open to competition, the development of this and other printing processes rapidly increased. In the 2010s, various metalworking forms of 3D printing were introduced, though limited, as were 3D printing of other materials than polymers, such as ceramics.

 

2012: Filabot, a 3D printing and filament company, developed ways for FDM and fueled filament fabrication (FFF) printers to utilize a broader range of more durable plastics.

 

2014: Dr. Manos M. Tentzeris and Dr. Benjamin S. Cook, working at the Georgia Institute of Technology, displayed the first use of new 3D printing software technology. This was a vertically integrated printed electronics additive manufacturing platform (VIPRE) that allowed the 3D printing of electronics with operational capacity up to 40 GHz.

 

Since 2014, software programs and 3D printing tools have been developed to even greater capabilities, and commercial consumer 3D printers have saturated the market. At MultiSource, the use of 3D printing is a key tool in the manufacturing of precision-based prototyping.

The Use of CNC Machining for Peripheral and Face Milling

When it comes to machining, there are many types of operations that can be utilized across manufacturing industries. Milling in particular is a highly versatile operation applied on CNC machining operation floors in the majority of fabrication facilities.

 

The precision, flexibility, speed, and quality that CNC milling provides is vital to the operations of the MultiSource Manufacturing LLC network. As a contract manufacturer, we are dedicated to providing comprehensive fabrication and assembly services from start to finish of any project, including complete CNC machining capabilities, engineering and design, a Class 1000 clean room workspace, plastic fabrication capabilities, finishing services, and much more.

 

Within each type of CNC machining operation, there are even more specialized techniques that can be applied depending on the format, materials, and desired end result. Milling, for example, has two primary techniques applied to the majority of situations when milling is appropriate. These two primary techniques are face milling and peripheral milling.

 

Face Milling

This milling operation works with the cutting mill positioned to be perpendicular against the component that will be worked on. The cutting mill spins on a central axis and moves to cut away sections of the component with its perpendicular motion. Face milling is considered to be the most common format for CNC operations. It is highly effective for rapid heavy-duty milling, high-feed milling, and other general face milling processes. Mills will typically use cutters at a 45º angle, but square shoulder and round insert cutters or side and face mills are utilized in other specific applications. 90º cutters are also useful for machining thin-walled components or components with weak fixtures.

 

Peripheral Milling

In contrast to face milling, peripheral milling places the cutting mill parallel to the component that will be machined. The cutting mill spins on an axis parallel to the component as it cuts away material from the work surface. When the mill is positioned this way, the full sides of the cutting mill are being applied to the work surface. This makes peripheral milling much more effective for rapidly removing large amounts of material from the work surface. Because of this, peripheral milling is useful for fabricating a basic component shape quickly, readying it for finer operations. It’s also used in large-scale milling or milling harder materials.

 

For visual reference, this diagram of peripheral and face milling shows a basic format for both CNC operations. Both face milling and peripheral milling are critical CNC machining operations used daily throughout operations in the MultiSource network. Our fully outfitted fabrication facilities have complete CNC machining capabilities in addition to our comprehensive design/build services.

Back to the Basics: Subtractive CNC Machining Operations

Machining operations of various types have been used in industrial settings for over 200 years. In the past 30 years, machining operations have developed exponentially to be faster, more precise, and capable of handling a wider range of materials. With the creation of digital technology and software systems, machining across industries is automated with computer numerical control (CNC). CNC machining is a highly accurate method of altering materials and fabricating even the most complicated parts. MultiSource Manufacturing LLC provides a wide range of services as a contract manufacturer, and CNC machining is a specialty across our six facilities.

 

The MultiSource network has been in operation for over 20 years, and our CNC machining capabilities have developed alongside computer technology, wireless network communications, and equipment improvements. Because of our experience and comprehensively outfitted machining production line, we can provide complete CNC machining services on multiple axes with quick, precision-based operations based on intelligent engineering designs.

 

Our facilities are outfitted with 140 CNC machines that all customers partnering with the MultiSource network can benefit from. Our CNC machining capabilities include 3-axis and 5-axis indexed milling centers as well as 80 mills, 20 Swiss machining centers, and 40 lathes all with vertical, horizontal, or multi-axis movement.

 

With a comprehensive repertoire of CNC machines, basic subtractive machining operations are all in our tool box for infinite combinations in manufacturing virtually any part. Basic, universal machining operations include:

 

  • Cutting: Cutting tools utilize one or more cutting edges that are harder than the component material. Single point tools and multi-cutting-edge tools are two standard cutting tool styles. Both perform more specific types of cutting operations. For example, single point tools perform planing, boring, and turning, while multi-cutting-edge tools perform drilling and milling.

 

  • Drilling: CNC drilling machines manufacture circular holes with two to four helical cutting edges. The drill operates parallel to its rotational axis as it is applied to the component.

 

  • Turning: A turning machine subtracts material from a component surface. A component is held on an axis and turned as a cutting edge removes material in a computer controlled pattern with precision and speed.

 

  • Reaming: Reaming machines are a valuable addition to any precision-based operation floor. Reaming serves to remove miniscule amounts of material from a drilled hole to create a specific size cut.

 

  • Boring: Boring is also used to finish roughly made holes with a bent single tip. The tip is advanced spinning into the pre-made hole and the cut is fine tuned. Boring is highly useful in precision machining and finishing operations.

 

  • Milling: Milling is applicable to the fabrication of many components. A mill with multiple cutting edges is slowly applied to a component surface and that component rotates on an axis. Both peripheral and face milling (cutting parallel versus perpendicular) are utilized on MultiSource operations floors.

Benefits of Reverse Engineering for Semiconductor Electronics Manufacturing

When it comes to electronics manufacturing, extreme precision is needed to build a reliable, high-quality product. Printed circuit boards, electromechanical components, semiconductors, and any other part that goes into a full electronic assembly demands an exacting, well-tested design.

 

For over 35 years, MultiSource Manufacturing LLC has provided that level of precision in our electronics manufacturing, using reverse engineering to structure informed, pre-dissected design specifications. Our team of knowledgeable, experienced engineers applies reverse engineering techniques to the design of semiconductor components and other electromechanical parts and assemblies.

 

Reverse engineering provides a valuable analytical resource to our design technicians and engineers for a range of applications. By taking apart the physical parts of a component as well as the data of use and the theory of function, engineers are able to work backwards from a final part or assembly to reverse the design and start from the beginning with a usable analysis.

 

For semiconductor component design, reverse engineering gives our engineers a way to work backward from an existing design that fits a specific application and adjust certain aspects of it if needed, overall continually improving the component as a whole.

 

Using reverse engineering to take apart the parts of a semiconductor component or full assembly gives our engineers the information they need for design improvement, including:

 

  • theory in the design of parts and their operation
  • materials used and how they react to long-term use
  • overall structure of interior and exterior
  • manufacturing process
  • assembly order of operations
  • how an assembly reacts to stresses in operation, both expected and unusual
  • any other information that adds to our engineering database about the form and function of a part and a full assembly

 

With reverse engineering providing this information, our design team has several benefits to work with. First, they can save time in the engineering process because they are able to pull from a wealth of data gathered from the analysis of a part. This in turn saves costs of building unnecessary prototypes.

 

Secondly, our engineers can build higher quality parts with a range of improvements made to every aspect of the full assembly. This often eliminates time, energy, and resources spent on testing and inspections during final quality control processes. With a better product made more efficiently and quickly, our electronics engineers can improve your production schedule by improving our own.
