During pre-design phrase, we go through the details with customers for injection mold making, such as parting line, gate position, draft, ejection, etc.
Considering the large quantity demand, hot nozzle was used to increase the productivity and save runner bar resin wastage.
Lead time for an injection mold like this needs around 20-25 days, but given customer's urgency, we push in the schedule into 15 days, this is a quite a typical situation when we deal with some companies who are in electronic consumer products business, new hot-sell items emerge quick but also fade away quick always, so timing is critical besides the quality satisfaction.
