Medical Parts Contract Manufacturing


The medical sector encompasses a diverse range of products, including numerous metal components. Contract manufacturers must adhere to manufacturing specifications rigorously for health and safety reasons. Rely on Bunty LLC to help your enterprise generate high-quality metal medical part components.


An Overview of The Medical Parts Contract Manufacturing Industry

Contract medical manufacturing is a highly specialized field that requires strict adherence to design and materials specifications for health and safety reasons. Bunty LLC offers contract manufacturing processes, but also offers prototype testing and robust quality control, as both play vital roles in the production of well-made, durable medical parts.

Today the medical parts contract manufacturing industry spans a wide selection of different products and materials. Companies engaging in this field produce goods as varied as surgical tables, gurneys, medical implants, anesthesia machines, hearing aids, syringes, external skeletal fixators, oxygen tanks, fluid pumps, and pacemakers. Medical metal parts contract manufacturers may generate components for complex mechanical assemblies or focus exclusively upon the production of a specific device. For safety reasons, medical parts typically must meet tight tolerance parameters and conform with extensive manufacturing materials specifications.

For example, the intended use of a metal medical part strongly influences the selection of its constituents. Some patients suffer severe allergic reactions to certain metals. Additionally, protracted contact with metal alloys proves deleterious over time if these materials begin breaking down inside the body. Consequently, when developing prototypes, medical parts implant designers must exercise care to prevent inadvertent patient metal poisoning. Designers also strive to create strong surgical implants which will retain desired shapes and not break or lose dimensional integrity over time. Gold and titanium have both gained popularity as implant constituents for these reasons.

By contrast, metal parts intended for use in external medical devices frequently require physical properties such as strength, tensile strength, and the ability to withstand heavy wear. They must autoclave readily and tolerate the repeated application of chemical cleaning agents, too. Stainless steel achieved widespread popularity in some medical devices and tools primarily due to these important properties.


Manufacturing Processes Utilized to Create Custom Medical Parts

Many processes enter into skilled contract manufacturing. During the production of metal parts for the medical industry, the specific technologies utilized by any contract manufacturer hinge upon the nature and intended use of a component. Some widely relied upon manufacturing processes include:

Metal Stamping: Typically during this process, a manufacturer uses single or multiple steps to form sheet metal into desired shapes. Stamping combined with automated assembly line production methods permits a manufacturer to generate a high volume of parts during a single run. Rely on Bunty LLC’s excellent metal stamping capabilities to assist you in mass producing required medical industry components.

Injection Molding: Usually utilized to generate low-cost plastic parts, today injection molding typically occurs in highly automated, computer-controlled environments. Injection molding machines help manufacturers infuse hot plastic into metal molds or dies at a rapid rate of speed and then eject the partially or fully formed workpieces to finish cooling. This technology frequently produces thousands of small components during standard production runs. It helps generate syringe barrels, plungers, seals, flanges, and numerous other small (and frequently disposable) medical parts.

CNC Milling: During finishing, an automated computer numerical control operated rotary cutter takes away materials from the surface of a workpiece, creating the desired texture. This subtractive process usually involves the use of multiple cutting blades. The process potentially speeds the creation of various components in high volume manufacturing environments. For example, it facilitates the mass production of medical alert bracelets and badges, rolling metal supply cart shelves, and some surgical instruments.

Turning: The turning process occurs during numerous kinds of finishing operations. A medical parts manufacturer may turn a workpiece against a cutting blade in order to shear away material and leave a cylindrical form displaying grooves, tapers, or slots.

Rapid Prototyping: Our rapid prototyping services enable our customers to create initial models of proposed products very quickly. While the process of obtaining regulatory approval for some medical devices takes years, inventors generate working models for market testing purposes rapidly when they rely on Bunty LLC.

EDM Wire Cutting: This machining process involves the use of an electrical current to help a machinist cut and shape a workpiece, usually during finishing. It results in the manufacture of metal components within tight tolerance ranges.


Frequently Used Metals And Metal Alloys

As a complex economic sector, the medical field requires a wide variety of different materials for use in medical devices and tools. Stainless steel, carbon steel, gold, silver, titanium, copper, aluminum, zinc, and nickel alloys have achieved particular significance during recent years. The selection of constituent raw materials for a medical device depends upon its product specifications and regulations. For example, federal regulations frequently impact the requirements in the United States.


Some Examples of Medical Metal Parts

Currently, the custom metal parts generated for the medical industry occur in a wide array of dimensions and conformations. They range from simple surgical suture and clips to complex mechanical components and electrical circuits built into sophisticated diagnostic equipment. The specific use of a particular metal part determines its constituents and physical properties, of course.
