1. Q: What kinds of software you are using?
A: AutoCAD, IGES, ProE

2. Q: What is the turn around time for your quotes?
A: Normally,  24 to 48 hours.

3. Q: Do you provide samples?
A: Yes, samples will be submitted no matter big or small orders. And we will begin the mass production after the sample is approved.

4. Q: How long does it take to complete the samples?
A: It varies widely by the different process.

-If investment casting parts, 3~4 weeks for mold and 2~4 weeks for samples.
-If sand casting parts, 3~4 weeks for mold and 2~3 weeks for samples.
-If forging parts, 3~4 weeks for mold and 1~2 weeks for samples.
-If stamping parts, 3~4 weeks for mold and 1~2 weeks for samples.
-If machining parts, 2~4 weeks for samples.
-If welding parts, 1~2 weeks for samples.

5. Q: Can you make the prototypes as per the sample?
A: Yes, we can. The drawing can be done by our engineer and forwarded to you for confirmation before making the prototypes.

6. Q: If samples are not OK, what to do?
A: If the samples are not passed after 3 times due to our reasons, we will refund it.

7. Q: If I am ordering samples, do I have to pay for them in advance?
A: If this part must be made by mold, the customer need to pay 50% deposit for tooling cost, and the balance upon sample approval. But if only machining parts, you can clear it up after samples are confirmed.

8. Q: What is the mass production lead time?
A: -New parts – The time varies by product. If it is required tooling, the time from initial PO to sample approval is 6 to 8 weeks. Production lead time is about 4~6 weeks from sample approval.
-Existing part – It is about 6~8 weeks from the initial PO.

9. Q: Do I have to worry about running out of parts?
A: Generally, customers give us the order at the beginning of every year, so we can arrange the production schedule and ship them as per your instruction at any time.

10. Q: What about quality, do I have to worry about quality?
A: We use qualified ISO 9002 or TS 16949 suppliers. When we are awarded a part, the first thing we do is to define the critical characteristics, quality requirements, delivery issues, packaging, past problems and any other relevant issues. All samples and documentation are confirmed before being sent to our customer.

11. Q: Do you accept small quantity?
A: That is OK. Normally, we will run a small production order in accordance with our customer requirements just to check packaging and conformance under production conditions.

12. Q: What materials can be used in castings?
A: Casting materials include carbon steel, stainless steel, and tool steels.

13. Q: Where are stainless steel castings typically used?
A: Stainless steel castings are put to use throughout various industries. They are commonly used in food processing equipment, valve components, power generation equipment, hydroelectric facilities as well as petrochemical and heat treat furnace parts.

14. Q: Why is investment casting called the lost wax process?
A: During the investment casting process a part pattern is made out of wax. The wax part is coated with a shell (usually ceramic) and heated to melt the wax out of the center. Once the wax is lost, molten material is poured into the cavity where a metal part is formed.

15. Q: What is sand casting?
A: Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. It is relatively cheap and sufficiently refractory even for steel foundry use. A suitable bonding agent (usually clay) is mixed or occurs with the sand. The mixture is moistened with water to develop the strength and plasticity of the clay and to make the aggregate suitable for molding. Over 70% of all metal castings are produced via a sand casting process.

16. Q: When should you use investment casting?
A: Investment casting is best used when the part design calls for complexity and close dimensional tolerances. It involves more steps than sand and various other types of castings. In addition, investment casting can be used to create thinner sections of metal and requires little surface finishing and only minor machining.

17. Q: When should you use sand casting?
A: Sand casting is used to make large parts. It is less expensive than investment casting, but the surface is rougher. Products made through sand casting may require additional finishing before it is completed.
