Part of Housing-Top is sucessful case in Topsun Mould. This part flatness is required by 0.5mm and customer had a failure experience in another suplier. When customer asked us for suggestion about this parts, the engineer according to experience and also made the mold flow analysis to supplied best suggestions. Customer was worried about it and we made very detailed plan for customer, we persuade their team to trust us and try it because we had similar part experience. 6 weeks later, we get good samples in T1 and control the flatness is 0.32mm. Of course it is a good news for customer, they are satisfied with our working and very thankful about it, and get the result from customer. Topsun Mould also very happy that customer trusted us and give us a chance to design it. 

Part of Fresnel Lens is very strict for light. Engineer and designer according to experiences to supplied suggestions for this part, because this part is thick and will caused sink mark, so customer according to our suggestions to optimized the part(don't change the function for this part). We used advanced machine to process and have to meet the optical requirements, after T1 sent the samples to customer to measuring and test, the dimensions and transmission of light are all OK, both of us happily ship the mould to Germany by Air flight.

Part of 45°ELM 120 Lens, has 5 exchangeable inserts, the thickness requirement is high, because it will affect transmission of light, so we have to consider more about it. Before we made DFM and 3D design, we have to consider runner, cooling, air venting, etc. Then we used mirrow EDM process and optical polishing. After T2 mould test we get good samples and solved the sink mark and bubble issues.
