This notice applies to information sent through the website RFQ form, email, WhatsApp or WeChat for the purpose of discussing custom precision metal parts. The RFQ form may keep a draft of the fields you enter in your own browser so a reload or interrupted session does not lose your work. Drawings and the consent checkbox are not stored in that draft. You can clear the saved draft from the form at any time.
Information we collect
An enquiry may include your name, business contact details, company, project application, material, quantity, finish, tolerance, timeline, delivery destination, project description and any drawing or image you choose to submit.
How we use enquiry information
We use the information to review manufacturability, prepare or clarify a quotation, communicate about samples and production, and maintain commercial records related to your request. We do not use submitted drawings as public marketing material without separate permission.
Submission and communication services
Website submissions are saved in our access-controlled WordPress enquiry dashboard. Uploaded drawings are stored privately and can be downloaded only by an authorized administrator. Email notifications are separate from submission storage and are enabled only after delivery has been configured. If a submission cannot be saved, your form details remain in place and you can choose to open an email draft in your own application. WhatsApp, WeChat and your email provider process information under their own terms when you choose those channels.
Retention and security
Enquiry information is retained only for as long as reasonably needed to respond, evaluate the project, maintain relevant commercial records and meet legal obligations. Reasonable technical and organizational measures are used, but no internet transmission or email system can be guaranteed completely secure. Do not send information you are not authorized to share.
Your choices
You may ask whether we retain your enquiry information, request a correction or ask for deletion where applicable. Some records may need to be retained for legitimate commercial or legal reasons.
