Are You Still Struggling With These Issues?

For die casting factories, buying a mold is a major capital investment that affects your costs, lead times, product quality, and overall production stability. But working with the wrong supplier can lead to endless problems and hidden costs. Do any of these sound familiar?

◆ Cheap Mold, High Later Costs

You saved on mold price upfront — but now you're paying for endless repairs, downtimes, and reworks

◆ Short Mold Life & Cracking

Your molds wear out or crack in just a few months — and the replacement costs keep piling up.

◆ Delivery Delays & Missed Deadlines

Promised delivery in 6 weeks turns into 10. Your production line waits idle, and customers start complaining.

◆ Poor Size Stability & High Scrap

Parts come out with inconsistent sizes. Constant adjustments and rejects are killing your productivity.

◆ Endless Modifications

No Moldflow simulation. Poor design. Trial after trial fails, delaying your project by weeks.

◆ Slow or Poor Technical Support

Something goes wrong — but your supplier is slow to respond or doesn’t understand your process.

Essential Tests We Take Before Mold Export

In order to ensure every mold meets the highest quality standards and customer requirements, we take the following essential inspections before mold export.

1.Check the cooling system for sealing

Ensure there is no water leakage under pressure.

2. Verify the water connector type

Confirm that the water fittings comply with the customer’s specified model or standard.

3. Inspect the ball surface radius (SR value)

Make sure it matches the customer’s design requirements.

4. Check the slider with hydraulic cylinder

Ensure smooth and stable movement without jamming.

5. Inspect ejector pin movement

Verify that the ejector pins move smoothly and return properly without resistance.

Die Casting Mold FAQs

1. What materials are typically used for die casting molds?

We use high-quality hot-work tool steels such as H13, 1.2344, 8407, SKD61, and S136, depending on the alloy type (aluminum or zinc), required mold life, and surface finish requirements.
2. How can I get a quote for a die casting mold?

Simply send us your 3D files (STEP, IGS, or X_T) and 2D drawings with dimensions, tolerances, material details, and estimated annual volume. We’ll review the data and respond with a detailed quotation within 2 working days.
3. How long does it take to manufacture a die casting mold?

For standard aluminum or zinc alloy molds, the typical lead time is 4–7 weeks from DFM approval to the first T1 mold trial.
4. Who owns the mold after it's made?

The mold fully belongs to the customer who pays for it. We never reuse customer designs or tooling.
5. What industries do your die casting molds serve?

Our molds are widely used in automotive, electronics, lighting, medical devices, telecom, home appliances, and industrial equipment.
6. What is the expected mold life for aluminum and zinc molds?

Aluminum alloy molds: 100,000–150,000 shots
Zinc alloy molds: 250,000–300,000 shots
Actual mold life depends on the steel used, maintenance frequency, and production conditions.
7. Do you offer mold testing before delivery?

Absolutely. We perform full mold trials (T1), and provide casting samples, trial videos, dimensional reports, and die casting parameter sheets to confirm performance.
8. Can you build molds to international standards?

Yes. We manufacture molds based on DME, HASCO, and LKM standards, depending on your project’s requirements.
