What heat treatment services do you offer?
+
We provide vacuum hardening, oil quenching, tempering, normalizing, annealing and stress relieving for mold steels and other tooling parts.
Which materials can you heat treat?
+
We mainly process mold steels such as P20, 718, H13, S136, NAK80, SKD11, and related alloy steels. If you have another grade, send us the spec sheet and we will confirm.
What hardness range can you achieve?
+
For tool and mold steels we typically reach 30–60 HRC depending on the grade and application. We will set the hardness window according to your drawing or standard.
How do you control deformation and cracking?
+
We combine correct austenitizing temperatures, controlled quenching media (oil, air or gas), fixtures and tempering cycles to reduce distortion and avoid cracking, especially on large plates and complex parts.
Can you provide hardness and metallography reports?
+
Yes. We can issue Rockwell hardness results, micro Vickers case-depth profiles, metallographic photos and material chemistry reports from our OES spectrometer, as needed.
Do you accept small batches or sample pieces?
+
Yes. We accept one-piece samples and small trial batches so you can verify hardness, deformation and performance before placing volume orders.
What is the maximum part size you can handle?
+
Our furnaces can handle medium to large mold plates and inserts. Please send the length, width, thickness and weight so we can confirm which furnace and process route are suitable.
How long is the heat treatment lead time?
+
Standard heat treatment jobs are usually completed within 3–5 working days after parts arrive. Large volumes or special processes may take longer, and we will confirm the schedule when quoting.
How should I prepare drawings and requirements?
+
Please provide 2D/3D drawings with material grade, required hardness, critical dimensions, surface finish and any special notes on distortion control or clamping directions.
Can you handle machining before or after heat treatment?
+
Yes. We can rough machine before heat treatment and finish machine after hardening, so you receive ready-to-assemble mold components if needed.
