Reusable, White or Clear
Reusable molds for cold embedding made from sturdy, yet flexible, white or clear silicone.
Both sizes are 1" high with 3/4" internal depth. Internal dimensions are 2 -1/8 x 1" and 3 x 2".
Even in well-established procedures such as sample embedding, new developments are being made. Following a recently published development in sample preparation (see the 2020 article by Khatkhatay and Pichumani cited below, working with semiconductor flip-chip packaged devices), we have developed new silicone rubber molds for better performance, particularly in failure analysis.
These molds are designed for molding small samples, cross sections, or similar. In these types of samples the area of the sample makes up a small proportion of the surface area and polishing becomes limited by the large surface of embedding media. Also, with small samples it can be difficult to monitor the polishing progress.
These molds drastically reduce the surface area of exposed resin while providing a much better view of thin, tall samples such as electronic circuit chips and boards. The more economical volume of resin required and smaller surface area also results in a significant reduction in the consumption of polishing supplies.
The optimal sample size for these molds is 3/8" (10mm) or less in thickness (for cross sections). The central portion of the mold accommodates the device during the resin pour and set up. The large blocks on either side exclude resin to funnel it into the central channel around the device and into the channel around the perimeter. This reduces the surface area of the cast resin by up to 48%, with a dramatic reduction in the grinding and polishing time required to reach the feature of interest.
Resin volumes to fill molds (nominal): 8mL, 15 mL, 20 mL compares favorably with 20 mL, 30 mL, 50 mL for standard molds. These molds are compatible with any of our Embedding Resins.
For making cold embeddings with epoxy. Separate cap for easy removal. Use Mold Release before pouring resin. Sold in packs of 12 for 1", 1-1/4", and 1-1/2".
For making cold mounts with epoxy or acrylic resin in metric diameters. Their translucence makes them ideal for ensuring good penetration of the blue curing light to all regions of the resin in the mold when cured in the Kulzer Technotray® POWER Light Curing Unit or POWER LED. Separate cap for easy removal. If needed, use Mold Release before pouring resin. Sold in packs of 3 for 15, 25, 30, 40 and 50mm.
