PMIeng Technical Frequently Asked Questions (FAQ)

Sourcing & Objectivity

Do you have domestic sources for most casting processes?

Yes, we maintain a network of contracted domestic casting sources for most processes. If we do not have a contracted source readily available, we can typically provide a direct referral to a suitable partner.

How can PMIeng remain objective when sourcing a component?

We are an independent firm and are not employees or agents of any single manufacturing company or supplier. Our objectivity is guaranteed because our primary goal is to target the right process and the right source for your specific component requirements.

Design & Consultation

Can PMIeng help with prototypes?

Yes. We can usually produce a small quantity of samples or prototypes without requiring the upfront procurement of full production tooling, helping you validate your design efficiently.

Can I send a 3D model or drawing for review before having a meeting?

Yes. We highly encourage sending PDF drawings and/or STEP files for review prior to a meeting. This allows us to assess your needs and leads to a more focused and productive consultation.

What is the best way to start a conversation with PMI?

The best way to start is by scheduling a free, 30-minute Teams call or phone call. This allows us to quickly understand your project and provide immediate value.

Process Selection & Material Properties

What factors influence targeting the right process for a cast part?

The primary factors influencing the selection of the correct casting process are the part’s size, geometry, specific alloy requirements, and its anticipated usage or structural application.

Are steel forgings stronger than steel castings?

Forgings tend to be stronger across the grain (perpendicular) because they possess a linear grain structure. Castings have a neutral grain structure. Therefore, a forging is typically better when strength is required perpendicular to the main flow, assuming the casting is sound and has minimal shrink defects.

What is the best castable aluminum alloy for structural applications?

A356 is widely considered a very good aluminum alloy for structural applications when utilizing a gravity pour process. However, the resulting casting soundness (lack of porosity or defects) is often as critical to the final structural performance as the alloy choice itself.

Specialty Components

How can PMIeng help with specialty fasteners?

We provide sourcing and process expertise for specialty fasteners, which are typically manufactured using cold forming machines combined with secondary operations. We also maintain a close working relationship with specialized partners like AVK Fasteners.
