Q: Are you environmentally responsible?
A: Yes,
Q: What are the common casting defects and how do you prevent them?
A: The common casting defects and our methods for preventing them are as follows:
• Slag Inclusion: Slag from the molten metal is trapped in the casting, causing defects.
◦ Solution: Prevent slag inclusion by installing ceramic filters in the gating system to effectively filter out slag and impurities before pouring the metal into the mold.
• Sand Inclusion: Sand particles from the mold are embedded in the casting, resulting in surface defects.
◦ Solution: Minimize the risk of sand inclusion by ensuring that the mold and core are properly cleaned. When closing the mold, avoid scraping or damaging the sand core. Always clean the gating system and the mold thoroughly before pouring to remove any loose sand or debris.
• Porosity: Gas pockets or voids form within the casting due to trapped air or gases.
◦ Solution: To reduce porosity, control the quality of the furnace charge, ensure thorough core baking, and develop a rational gating system. Adjust pouring temperature and venting plans according to the casting’s structure to allow gases to escape.
• Shrinkage Cavity: A shrinkage cavity is a large void that forms due to the metal’s contraction during cooling. It typically occurs in the last areas to solidify, often leaving a significant cavity.
◦ Solution: To avoid shrinkage cavities, use the proper chemical composition in the molten metal, control the pouring temperature, and optimize the gating and riser systems. Adequate feeding systems ensure the metal fills the last solidifying areas, preventing voids from forming.
• Shrinkage Porosity: Shrinkage porosity refers to small voids that form throughout the casting as a result of the metal shrinking during cooling and solidifying. Unlike shrinkage cavities, the pores are smaller and often scattered inside the casting.
◦ Solution: Prevent shrinkage porosity by adjusting the pouring temperature and using the correct alloy composition to promote uniform solidification. Position risers and feeders properly to ensure the metal has a continuous supply as it cools, preventing void formation.
• Looseness: Looseness is a type of internal porosity caused by an irregular solidification process. It leads to weak or porous areas within the casting, reducing its strength and density.
◦ Solution: To reduce looseness, control the pouring temperature and solidification rate. Properly designed gating systems ensure the metal fills the mold uniformly, while using suitable mold materials helps regulate cooling and solidification to prevent porosity.
• Cold Shut: Occurs when two streams of molten metal meet but fail to fuse properly, leaving a weak or incomplete spot in the casting.
◦ Solution: Use a rational gating system and adjust pouring temperature based on material and wall thickness requirements to ensure proper fusion of the metal streams.
• Lack of Material: Missing material or incomplete sections due to improper mold filling.
◦ Solution: Before casting, check the mold for integrity and ensure no defects. Properly compact the sand and ensure the mold’s strength. Carefully check the core for excess sand or debris before assembly. Ensure a proper pouring speed, and avoid mold damage during boxing, cleaning, or grinding to prevent physical impact to the casting.
• Mold Swelling: Mold material swells due to moisture or thermal expansion, which can distort the casting shape.
◦ Solution: Select the correct sand box size according to the casting’s dimensions, choose appropriate steel plate thickness for the box to ensure strength, and compact the sand tightly to maintain mold integrity. After assembling the mold, make sure all fasteners are securely tightened to prevent any expansion.
• Sand Burn-On: Sand adheres to the surface of the casting, causing rough texture or surface contamination.
◦ Solution: Ensure cores are compacted properly in areas prone to sand adhesion. Use high-quality refractory materials and apply coatings carefully to ensure even coverage. Ensure the correct coating thickness and avoid over-spraying.
• Deformation: Castings may warp or distort due to internal stresses from uneven cooling or improper handling.
◦ Solution: Inspect the mold for deformation before casting. Ensure the mold’s base is fully in contact with the ground, and use wedges to secure it. Strictly control the resin sand curing time, and ensure proper contact with the ground to avoid suspended sections. Follow the recommended box-assembly time for different castings to prevent warping.
• Insufficient Pouring: The casting does not receive enough molten metal, leading to incomplete filling.
◦ Solution: Consider the weight of the product when designing the gating system, and select the appropriate pouring temperature and speed. After filling the mold, ensure that additional molten metal is added to compensate for shrinkage and maintain full metal flow to the mold.
Q: What are the typical tolerances for iron castings from XDL?
A: The typical tolerances for iron castings vary depending on the casting method, part size, and precision requirements. Here in XDL, the tolerance range for our iron castings could be from DCTG11 to DCTG13, according to ISO 8062-3 / (the Chinese equivalient is GB/T 6414) .
Below is a table summarizing the description of DCTG11 to DCTG13 as specified in the ISO 8062-3 standard. These grades correspond to dimensional tolerances for castings, representing increasing tolerance ranges for larger deviations from nominal dimensions.
