Q1.About inquiry?
A1:Our factory need to know:1.Size:drawing,or sample,and so on.2.Material:food grade,industry gradeor medical grade.3.Requirement:cutting,splice,printing,or any other.
Q2. Price on Made in China is purchase one?
A1:No,our factory mainly produce it according to requirements of customer,different requirement and purchase quantity will affect the priceso the online price are for reference only.
Q3. About OEM?
A1: If you can provide us the drawing format in JPG,AI,PDF,DWG,IGS,STEP,and so on,that would be best; if no drawing, it is ok to have sample;if no drawing and sample, you can tell us what you think about the product,and we can send the design drawing to you to confirm the size and structure of product,after confirm the drawing,then start to do the sample.
