  • Publication number: 20110293925
    Abstract: An object is formed on a component with a positive flash shut-off during insert molding operations. The mold has a base with a cavity and a port that delivers a liquid to the cavity. The base has a component support structure for supporting the component and pockets formed on opposite sides of the cavity. The pockets are slightly spaced apart from the cavity by thin partitions. Inserts located in the pockets and are formed from a polymer. Both the partitions and inserts comprise the component support structure. The inserts have a dimension that is smaller than that of the base and partitions so as to form a compression fit around the component to reduce or eliminate flash down the component during the molding process.

  • Publication number: 20090253785
    Abstract: A bactericide composition kills Staphylococcus aureus (S. aureus), Escherichia coli (E. coli), Methicillin-resistant Staphylococcus aureus (MRSA) and Propionibacterium acnes (P. acnes) and comprises a solvent and L-ascorbic acid. The L-ascorbic acid is dissolved in the solvent in a range of 1 wt % to 40 wt %. Ascorbic acid (vitamin C) is water-soluble and is essential for people. Thus, ascorbic acid contacting people will not harm them, and if a person inhales ascorbic acid, ascorbic acid will be metabolized and excreted out of person's body. Therefore, the bactericide composition is safe and not harmful to a person's health.
