Working Method 

1. Rapid Prototyping: 

Customer will send the primer drawings to Sunrise to make small quantity prototyping to check whether it's suitable for assemble and the function test. Normally customer need the rapid prototyping urgently, so usually we can send the samples to customer within 7 days.  

2. DFM: design for manufacture

Before start to make the die casting tooling, we will carefully check the drawing, and per our engineers more than 10 years strong R&D capability and rich engineering experience for aluminum die casting to analyze the drawing, and will submit the perfect DFM, we also can discuss with our customer together to solve key point that don't affect the part function and cost saving suggestions.

3. Start to Make Die Casting Tooling

When get the customer's agreements for our DFM, such as confirm the moving die and fix die, ejector pin location, slide, parting line, machining location etc. Then we will start to make the die casting tooling, and will send the die casting tooling schedule to customer, and every week our engineer will update the schedule, then send to customer and inform that we are on the schedule. If any question will delay the schedule, we will send the current conditions to customer in advance.

4. Trial Run the die casting Tooling

When finish the die casting tooling, we will arrange to trial run it, normally the first time we will trial run 10pcs of die casting raw material, then per the processes to follow each process, then send the samples to customer to approve it. Normally the lead time is around 2 weeks.

If the first trial run result wasn't good, we can modify the tooling in house, we have grinding, Milling, CNC, EDM machine in house, so we can quick responds to modify, then trial run again.

And if customer would like to ECN, it's also no problem for us, we can modify the ECN in house too.

5. FAI report and PPAP files

When we send out the samples, we will submit the FAI report and PPAP files if customer need it.

6. Mass production

When we get customer approval, we can start to mass production immediately.
