Ⅶ：Common Casting Defects & PRIME’s Prevention Strategy
Metal casting is a complex process that, if not tightly controlled, can lead to costly defects. At PRIME, we proactively prevent these issues through advanced tooling, strict process control, and real-time quality monitoring.
1. Blowholes appear in the casting
Description: Gas Hole is usually in the process of liquid metal cooling, due to poor exhaust or gas content is too high, resulting in gas trapped in the casting or surface, the formation of voids. This will seriously affect the strength and density of the casting.
PRIME Solution: By optimizing the exhaust system of the mold, controlling the pouring speed of the liquid metal, and adopting a strict smelting degassing process, the gas content is effectively reduced, and the formation of pores is prevented from the source.
2. Shrinkage cavity or porosity in castings
Description: In the thick wall area of the casting, due to the uneven solidification rate or the unreasonable feeding design, it is easy to form internal depression or insufficient density, which affects the structural strength and subsequent processing stability.
PRIME Solution: We use professional casting simulation tools for feeding analysis, optimization of riser and cooling system design, to ensure the smooth solidification of liquid metal filling, eliminate shrinkage and porosity.
3. How do cold shuts form？
Description: Cold shut is due to the low temperature or poor liquidity of the liquid metal, resulting in multiple strands of liquid metal in the mold failed to fully integrate, forming obvious seams or clamp lines, affecting the appearance and air tightness.
PRIME Solution: We strictly control the pouring temperature, improve the fluidity of the alloy, and optimize the design of the flow channel system of the mold to ensure the smooth filling of the molten metal and prevent cold shut.
4. Inclusion in the casting
Description: Slag inclusion usually comes from slag, oxide scale and other non-metallic impurities mixed into the liquid metal and deposited in the castings, resulting in material performance degradation and internal defects.
PRIME Solution: We use high-efficiency smelting technology and ceramic filter system to ensure the purity of molten metal, and control the flow rate and direction in the pouring process to prevent slag from entering the mold.
5. Surface oxide inclusions appear in the castings
Description: When the molten metal reacts with the air to form an oxide layer, which can not be separated in time, grayish-black spots or flaky inclusions will be left on the surface of the casting.
PRIME Solution: We reduce the formation of oxide layer by introducing protective atmosphere or covering agent in the melting and pouring process, and improve the gate design to reduce the contact area between liquid metal and air.

In Summary
Choosing the right metal casting supplier is a strategic decision that goes far beyond unit pricing. In this comprehensive guide, we’ve covered the essentials of casting—from core processes and material selection to quality management and global logistics. The key to success lies in selecting a partner who not only meets your immediate requirements but also supports your long-term growth and innovation.
Key Takeaways for B2B Buyers
- Technical Excellence is Essential: Modern casting applications demand advanced tooling, process expertise, and the ability to deliver consistent quality—from sand casting to investment casting for complex geometries.
- Quality Cannot Be Compromised: In today's competitive market, defects are costly. Choose suppliers with robust QMS, certified processes, and full inspection protocols including SPC, IQC, and final QA.
- Think in Terms of Total Cost: True value includes tooling, quality risk, delivery reliability, and manufacturability support. A slightly higher unit price may yield much lower overall costs.
- Value Strategic Partnerships: Work with suppliers who act as partners—those who understand your goals, provide proactive engineering input, and care about your product's success beyond simply making castings.
- Global Reach, Local Responsiveness: A great partner combines global scalability with knowledge of customs, compliance, and logistics—ensuring reliable delivery and adaptable service wherever you operate.
