Micro Injection Molding Medical Devices Utilize Micromolding for Injection of Dissimilar Materials

 

Micro injection molding is a molding process for the manufacture of plastics components for shot weights of 1 to 0.1 g with tolerances in the range of 10 to 100 microns. In this process, the material being molded is first liquefied by heating it to a specific temperature. This "plasticizing" action causes the compound to expand into its liquid form, while simultaneously solidifying at the same time. The result is a material with several tensile components that can be precisely cut and shaped without having to compromise its integrity or strength.

Micro injection molding medical devices are one of the application of micromolding. This process is commonly used as a building material for things such as computer enclosures and medical device exteriors. This very same technology can be applied to a lot more things, particularly in the medical device industry. There are several applications for micromolding. It can be used for the manufacture of parts that have complex surface geometry, like microphthalmological tools. It can also be used to create shells for firearms, or casings for surgical instruments. Even electronics like cell phones and laptops have parts manufactured this way.

Micro injection molding medical devices utilize micromolding for the injection of dissimilar materials. There are a few other medical applications for this molding technology. In certain circumstances, it can be used for tooling in machining, like forming tools from a variety of pieces. In more extreme situations, there may be a need to replace a tooling, especially if it has been subjected to harsh environmental elements. Micro micromolding can also be used as a temporary mold for tooling purposes in the medical applications mentioned above. This is a convenient solution for a number of companies, since they do not have to purchase new tooling for their projects.

One popular use of micro injection molding medical devices is in the production of plastic parts. In this case, the mold is made using a coated nylon mesh. Nylon is an extremely flexible material, but it can be difficult to form into a solid, consistent size. After the micromolding process is complete, the parts fit together tightly. The tight fit can be helpful for products meant to be shipped to large customers, since they will not have any "give" when they are first manufactured.

A third application of micro injection molding medical devices comes in the form of press molds. Press molds are used to create a consistent surface texture in a product. If a consumer tries to push a product into one of these molds, it will adhere to the mold like a vinyl sticker. The consistency of the mold surface ensures that no bubbles, lines, or inconsistencies show up, and that the item can be safely sent to customers.

Some of the medical applications of micro injection molding medical devices are used in the injection molding of plastic products. In the past, injection molding was only effective for plastic products with extremely low tolerance to extreme heat. Micromolding technology has improved over the years, making it easier for manufacturers to mold items into intricate details without risk of warping or cracking. In some cases, the mold is formed into exact dimensions, which prevents errors from creeping into the mold while it's being formed.

When designing micro injection molding medical devices, it is often advantageous to use micromolding. It offers a range of benefits to both designers and manufactures. From smoother texture to higher resistance to impact, micromolding can make a real difference in a product's ultimate effectiveness and reliability.
