I need a high-temperature resistant cast steel part. Can Matech provide a full-process service from material selection to finished product delivery?

2026-03-31
Absolutely. This is our core strength. The process includes:
1) Material selection: Recommending heat-resistant steel grades based on your working conditions (e.g., temperature, wear);
2) Casting and heat treatment: Using lost wax casting or investment casting, with normalizing, quenching and other treatments to optimize performance;
3) Precision machining: Conducted by the same project team, with a detailed process control plan designed to ensure consistent manufacturing benchmarks and final precision of products.
We also provide a complete set of quality documents.Including the dimensional inspection report & material certificate.

1
On food filling lines, apart from stainless steel, how is your chain designed for easy quick teardown and deep cleaning?
After full communication and customer approval, we can provide tool-free quick-release chain links and an open structure for you. These quick-release links let you quickly remove a section of the chain for cleaning or replacement without disconnecting the whole production line. The open structure ensures there are no dead corners where food residue or liquid can get trapped. All our designs follow relevant international standards, and we’ll also give you corresponding cleaning guidelines.

For the high-temperature zone of up to 800°C at the kiln tail of cement plants, how do your heat-resistant steel casting parts ensure no deformation and no loss of strength under high temperatures?
The key is using special-purpose heat-resistant steel material (e.g., ZG40Cr25Ni20) and precise heat treatment control. This material forms a stable oxide film on the surface with its high chromium (Cr) and nickel (Ni) content, and maintains the austenitic structure at high temperatures. We optimize its high-temperature creep strength by controlling the casting's cooling rate and performing solution treatment, ensuring it maintains dimensional stability and withstands thermal loads during long-term thermal cycling.

In the high-temperature, high-humidity and corrosive environment of a palm oil mill, how do your conveyor chains prevent premature rust and corrosion?
We can provide a combined "material – process – coating" solution tailored to this operating condition.
The chain is made of martensitic stainless steel or high-grade alloy steel, rather than relying solely on surface coating.
On this basis, a thick-layer Dacromet coating is applied, which can ensure good performance on salt spray resistance of more than 800 hours—far superior to conventional galvanizing. This can effectively resist erosion from palm fatty acids, high temperature and moisture.

If the trial-produced samples require modification, how will the relevant mold costs and modification cycle be handled?
If the modification is required because we did not meet the mutually confirmed technical specifications, we shall bear all related costs.
If the change is initiated by the customer as a voluntary design revision, we will assess a reasonble and nominal processing fee based on the modification scope, and clearly inform you of the impact on lead time (normally 3–7 working days). All costs and lead times will be confirmed in writing before any modification work starts, with no hidden charges whatsoever.
5
For overseas projects, what measures do you adopt to guarantee consistent quality for batch production?
We rely on the dual guarantees of "process standardization" and "batch traceability". First, the process parameters confirmed with samples are documented and formalized as standard operating procedures. Second, key production parameters and critical control characteristics (including dimensions) at all key stations are recorded in real time. Process parameters are adjusted promptly against standard procedures to ensure consistent quality and dimensional stability for each batch.
6
Before starting a custom casting project, will you conduct a formal review of mass production feasibility? If yes, what are the main review items?
Absolutely. We believe this is a necessary step to make sure the project goes well. The review will be done together by our casting, machining and quality engineers, and mainly check three key points:
1) Design manufacturability: whether there are blind spots that are difficult to cast or machine?
2) Cost and process: Is the process the most efficient and economical one?
3) Risk assessment: Identify potential quality risks points and make plans in advance.
We will also send the review result and improvement suggestions to you as an official document for your confirmation at that time.
