FACTORY LOCATION
Ask about a visit
Are you a factory or a trading company?A factory — 13 mill-turn and 16 Swiss-type machines in Dongguan, China.
NOW CNC is the export brand of Shenzhen Mingzhouda Hardware Technology Co., Ltd. The brand and manufacturing operation belong to the same company.
Factory address: Building 1, 1st Floor, No. 20 Weixing Road, Chashan Town, Dongguan, Guangdong, China.
What sizes can you make?Ø0.5–200 mm (0.02–7.87 in) outside diameter, with part length ≤ 300 mm (≤ 11.81 in).
Our batch focus is Ø1–100 mm (0.04–3.94 in) parts in runs of around 2,000 pieces.
Why is unit price lower at 2,000 pcs than at 200?One setup is shared by ten times as many parts, so each carries 1/10 of it.
This is setup arithmetic, not an actual unit-price ratio; material and cycle time per part do not fall in the same way.
