What is medical plastic injection molding?

SPARK' injection molding services can be used to create plastic parts and components for medical devices. We can create any number of specialized medical plastic parts molding and plastic injection molding, either as subassemblies as components for more complex instruments. Medical Plastic Parts Molding Medical Grade Plastic Resins SPARK has a number of different materials available for our medical plastic injection molding processes, making it possible for us to find the ideal material for your project's needs. We use engineering resins such as polycarbonate, PEEK, and Ultem, which offer excellent mechanical properties and high tensile and temperature load ratings to resist breakage and deformation due to heat. We also use a number of specialized polymers with resins or fillers built in, such as fiberglass carbon fiber, talc, or custom color compounds, to give the completed product mechanical advantages or other unique properties. Our expertise with [...]

6 Common Injection Molding Defects

When working with any manufacturing process, a number of defects unique to that process commonly occur. This is true across many processes and industries, including plastic injection molding and high volume injection molding.                          Plastic Injection Molding Delamination Delamination, when a finished part has a layer of flaky material at the surface, hurts both aesthetic of your part and its strength. Caused by moisture contamination of the resin pellets or by other contamination of the melted resin with a dissimilar resin, or by release agents in the mold, delamination is the result of the resin being prevented from bonding. Discoloration Discoloration is simply when a finished part is a color different than intended                       Plastic Injection Molding Burn Marks Burn [...]

How to Design a Die Casting Mold?

Die casting is a technique for mass-producing metal products and components. Die Casting Mold design is one of the most important steps in the process because the shape and attributes of the mold will directly affect the final product. The die casting procedure forces molten metal into molds using high pressure and it requires a mold with exact specifications to achieve the task. The Importance of Die Casting Mold Design Die Casting Mold Die Casting Mold design affects the shape, configuration, quality, and uniformity of a product created through the die casting procedure. Improper specifications can result in tool or material corrosion, as well as inferior product quality, while an effective design can improve efficiency and production time. There are a number of mold design factors to consider when deciding on the appropriate specifications for a project. Some of these factors include: Bosses [...]

Properties of Choosing Materials for Mold

Choosing materials for injection mold making is very critical. If the materials are not excellent enough, workpiece made by mold has poor performance. So, materials used for mold processing should meet the following six properties: 1. Strong tenacity Most of working conditions of molds are very wicked. Some of molds are usually suffering from larger impact load, which results in brittle rupture further. To prevent mold parts from rupturing suddenly during operation, the mold should have higher intensity and tenacity. Tenacity of injection mold mainly depends on carbon contents, grain size and texture of materials. 2. Cold and hot fatigue resistance Some molds are located in a status of being heated and cooled repeatedly, so that surface of cavity is impacted by tensile force, pressure and varying stress, which cause cazing and spalling on surface, increasing friction force, hindering plastic deformation and reducing the dimensional [...]

Silicone Rubber Mold Manufacturing You Should Know

Silicone Rubber Mold, with its low compression set, fast cure cycles, great stability and ability to resist extreme temperatures of heat and cold makes it ideally suitable for the production of parts where high quality is a must. Unlike most thermoplastic elastomers (TPRs and TPEs), LSR remains flexible and elastic down to -70o F and retains its properties up to 450o F. In addition to these qualities, the wide range of hardness and colors, silicone elastomers have become the material of choice for an ever increasing amount of applications. Do not have your liquid silicone rubber mold built by a plastic mold maker. Liquid silicone rubber is a totally different mindset. SPARK Mold and Engineering is one of the few companies in the United States offering waste-free liquid silicone rubber molds for over 28 years. Waste-free molds coupled with various types of automation devices, such [...]
