Why Zinc Quality Needs Multi-Stage Inspection

In the manufacturing process, quality is not the result of a single test, but instead comes from several steps of quality checks. This also applies to zinc die casting components, where each inspection method serves a specific purpose and has its own limitations.

At PT Cipta Orion Metal (DESTEC), zinc materials used for gas regulator components undergo multiple testing stages to ensure durability, safety, and long-term performance as part of an enhanced Destec Dual Quality Control process.

Zinc Quality Cannot Rely on a Single Test

Zinc die casting may naturally contain porosity as a result of the manufacturing process. However, not all porosity has the same impact, and not all defects can be detected through a single testing method.

Testing focus may vary depending on:

1. Surface condition

2. Readiness for the finishing process

3. Specific technical requirements

For this reason, relying on only one test is not sufficient to represent zinc quality as a whole.

The Importance of a Multi-Stage Approach for Regulator Components

In regulator applications, material quality is not only about appearance, but also about performance consistency, functional reliability, and failure risk control.

A multi-stage inspection approach helps ensure that each production stage is evaluated according to its function, potential risks are identified early, and quality decisions are made based on proper technical context.

This approach forms a critical foundation for meeting regulatory expectations, industry standards, and safety requirements.

Two primary tests are applied: corrosion testing (immersion test) and porosity testing.

Stage 1: Zinc Corrosion Testing (Immersion Test)

Zinc materials undergo corrosion testing using a 5% NaCl solution. The use of 5% NaCl solution was chosen because the test replicates real kitchen conditions. The regulator has consistently demonstrated durability over the years, even under exposure to saline cooking fumes and high humidity.

The main purpose of corrosion testing is to measure the corrosion rate of zinc material under controlled conditions that simulate real-world usage environments.

Different zinc composition combinations are tested to:

1. Observe material degradation speed

2. Compare corrosion resistance between formulations

3. and Evaluate zinc performance under corrosive exposure

According to the R&D Team of Destec Indonesia:

“Corrosion testing provides quantitative data on material degradation rate. This allows us to project service life performance and ensure that the selected zinc formulation meets regulator application requirements.”

In other words, this test is not intended to answer whether a material simply “passes or fails,” but how long the material can be used safely and optimally.

Stage 2: Porosity Testing

Porosity testing is conducted to detect micro pores or small surface defects in zinc that are not visible without testing aids.

This inspection uses a spray-based method with three spray variations, aimed at evaluating:

1. Zinc coating uniformity

2. Surface quality of the material

3. Areas with potential risk of leakage or functional failure

By conducting this test at an early stage, potential defects can be stopped before the material proceeds to the next production process.

Relevance of Corrosion and Porosity Testing for Regulator Products

Several key conditions must be considered in gas regulator usage:

1. Long-term operation

2. Safety-related risks

The combination of corrosion testing and porosity testing ensures that zinc materials:

1. Have proper surface integrity

2. Are resistant to long-term degradation

3. Are suitable for use in compliance with existing safety and regulatory standards

Commitment to Product Reliability

For us, quality is not only about the final result, but about how that quality is built. Multi-stage inspection is part of an ongoing effort to maintain consistency, reliability, and trust-especially for regulator applications where performance and safety are critical.
