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.
Rubber parts are notoriously difficult to run in a tumbling process. Before tumbling, you can see the parting line at the inner ring and outer ring. For this part, the goal was to remove the mold parting line …
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 ...

To tackle the issues of low efficiency and inaccurate results in the automated grinding of large castings, this paper presents a pioneering technique for generating grinding paths.
Large complex forgings play a vital role as major load-bearing components in industries such as energy, ships, transportation, and more [].After the forging process, various random defects of different sizes, such as parting lines, flashes, oxide skins, and local deformations, remain and need to be addressed through grinding as an essential …
The burr standard can reach the first-class standard: none; the second-class standard is less than 0.2mm; the second tool is a grinding machine, which can remove parting line burrs, ejector marks, convex hulls, tortoise cracks, typing surface burrs, and even polish The effect; the third type is the belt machine, which can remove the parting
Check out the #ROKAE XB7 #robot in action, performing parting line #grinding of injection-molded auto parts with high precision and efficiency. This robot has been running trouble-free for four ...
Cracking the cap leaves a slightly irregular mating surface between the rod cap and rod. The cap only fits one way because the parting line is unique to each rod. Consequently, if the bore is out-of …
The parting line is the boundary between the two halves of the injection mold, and it is where the two mold halves meet during the molding process. Proper attention to the design of the parting line is essential to achieve smooth mold closure, prevent flash or burrs, and ensure efficient ejection of the molded parts. ...
We operate a CNC controlled MAUS auto grinder for fast consistent finishing of even the most difficult parts, or Fox 30″ snag grinders along with a wide variety of hand held grinding tools depending on the needs of our customers. Check gauges are used on many parts to ensure contacts and parting lines are removed properly.
While selecting a parting line should be relatively simple, several parting line choices often could be used, and determining the proper parting line location on a …
Does a Parting Line Affect Injection Molded Product's Quality? Properly constructed parting lines can undoubtedly impact the visual quality of the finished product. Most people need to realize that a poor parting line can also affect strength and durability. A final part's wall thickness is often only a few millimeters or 1/8-inch, and poor ...
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.
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 ...

Additional grinding will be performed only when specified. In the absence of specific requirements it will be considered normal to blend excess material into the ...
the parting line) is larger than that in the vertical direction. Otherwise the bearing eccentricity required for establishing stable hydrodynamic lubrication may be too low. The maximum out-of-round is 0.001". Recommendations for maximum misalignment of the bores: For tri-metal bearings: 0.001" overall value; 0.0005" on adjacent bores.
Once the castings are separated from the trees or risers, all flash and parting line metal must be removed. Each of these is a result of casting through the use of compacted molds. Depending on the casting finish …
3. Sprue, Parting Line and Other Flaw Removal . When a casting is cut from its tree, there still remains a bit of the sprue left (no matter how close you cut to the ring). This remnant of the sprue must be removed, and …
