Need for Investment Casting Increases for Medical Applications

Admin    May 24, 2018

operating-room-medical-equipmentCustom investment casting is used in many medical products that aid in the increasing quality of care patients receive, time spent in recovery, and the prevention of complications. The science is responsible for some of the greatest achievements in modern medicine, including knee and hip replacements. A recent study about knee and hip arthroplasties found that 7.2 million Americans have an implant. It’s estimated that between 2005 and 2013, the number of total knee replacements in the U.S. will increase by 600 percent. Hip replacements will increase by about 200 percent over the same period. Investment casting manufacturers have an important role in the health of Americans as they continue to produce innovative replacement parts and components for the medical devices that heal them.

Investment Casting Overview

Investment casting is a time-tested metal-forming technique. It involves the creation of a three-dimensional wax pattern to make a mold, or investment. After completing the mold, a manufacturer melts the wax inside and pours molten metal into the cavity. When the metal hardens, the manufacturer removes the investment to reveal the cast part.

Why the Need for Investment Castings Will Increase in the Medical Industry

Factors driving the demand for custom investment castings in the medical community include innovation, the increasing need for healthcare professionals, and health trends. Technology is a fast-paced field, and the medical industry is quick to follow the latest innovations. These innovations require the help of investment casting manufacturers to make prototypes and mass-produce the components necessary for patient care and therapeutic technologies.

The addition of 2.4 million jobs is the result of an increased demand for medical care as Baby Boomers age and the population grows. As the demand for healthcare rises, so will the need for basic investment-cast components found in clinics and operating rooms.

The average age of patients requiring joint-replacement procedures, such as knee and hip replacements, has decreased. Surgeons also replace ankles, wrists, elbows and shoulders using investment-cast components. The average age of patients undergoing hip replacement surgeries has fallen from 66 to 65. The average age for knee replacements declined from 68 to 66. The age decline could be an indication of a more active lifestyle among seniors, as well as increasing obesity levels. While age the declines are small, it is important to note that the components used in replacement surgeries have a lifespan of about 20 years. Therefore, patients electing to have joint replacement surgery at a relatively young age face the possibility of a repeat procedure in the future.

As healthcare providers work toward mitigating negative patient outcomes by improving the performance of implant devices, foundries are naturally at the forefront of medical developments.
