Mastering Wastewater Systems: Essential Insights into Maintenance, Life Span and Chemical Impact In this high-level overview of wastewater system maintenance and upgrades, Robin Deal and Brian Greene will review the critical components required for a fully-functional system and discuss their expected life span.
A curved parting line deviates from a straight line and follows a curved path along the mold. It is commonly used for molds with intricate or organic shapes where a straight parting line would result in sharp corners or edges on the final part. 4. Stepped Parting Line. A stepped parting line has multiple levels or steps along the mold surface.
Fins and burns are one of the most commonly occurring casting defects. Also known as flash, it is unwanted and additional material attached to the casting metal. It is typically formed by a thin sheet of metal that forms at the edges of the parting line. It is a waste material that turns into slag after melting.
When finished grinding, clean bolt holes to remove any chips or debris that may have accumulated then install new bolts. Parting Edges. As stated before, most of the connecting rods you will deal with have a straight parting edge. You may also come across rods with Tongue & Groove (T&G), Serrated or Fractured parting edges.

Parting, Parting Off Parting, also known as parting off, is a lathe machining operation used to cut off a workpiece from a larger stock material. The primary purpose of parting is to separate a finished or semi-finished component from the rest of the material, creating individual pieces with specific lengths.
Parting Line Mismatches. When the two halves of the mold don't match perfectly, it creates gaps for molten plastic to escape, leading to flash formation. Improper Venting. ... Grinding is another technique used to remove flash from injection-molded parts. This method involves the use of tools or grinding machines to carefully shave off the ...
Parting Lines. When referring to injection molded parts, the phrase "parting line" refers to a line on the part that is created where the two halves of the mold come together. What results is a faint, sometimes unnoticeable line on the part. This line usually doesn't affect the overall shape or dimensions of the part, but can be visually ...

The determination of where the parting line will be located on a casting design seems innocuous, but the parting line can affect the cost of the pattern equipment, the number of cores used in the design, the ability to easily remove the pattern from the mold, grinding and finishing costs and potential scrap rates.
The alternate classes of parting lines are called either "straight" or "broken" for brevity. Regardless of whether draft is applied or natural, the forging will have its maximum spread or girth at the parting line. Proper placement of the parting line ensures that the principal grain flow direction within the forging will be parallel to the ...
