Who makes it?
Who checks it?

Vango is an engineering-led manufacturing partner with its own CNC machining and mold design-and-build floor in Qingdao. We take CNC and tooling orders directly. For confirmed specialist routes including investment casting, plastic injection molding, glass pressing and blowing, and rubber or silicone molding, we define the drawings, tooling, production specifications, and inspection criteria with the customer, then manage a qualified factory to execute them. Vango remains your accountable partner.

A specialist glass factory manufactures the glass parts. Vango aligns the product requirements with you, controls the drawings, tooling, and approved samples where required, defines the production and inspection standards, manages trials and production, and accepts the result against the agreed criteria.

A glass factory is optimized for glass production. If you already have complete drawings, proven tooling, production parameters, and an inspection plan, direct sourcing may fit. If those pieces still need to be defined and aligned across the whole product, Vango provides that engineering layer and remains responsible for the result.

Yes. Send the drawing, material, quantity, and inspection requirements. We accept standalone prototype, first-article, and production CNC projects.

Yes. We accept standalone mold design, manufacturing, modification, trial, and validation projects. The exact scope and mold ownership are agreed before work starts.

We agree the acceptance criteria before production, release controlled drawings and approved samples, manage trial and first-article reviews, and inspect the production result against the agreed plan. The exact inspection method depends on the product and is confirmed in the project scope.

The party that pays for the tooling owns it, unless the project agreement says otherwise. Storage, maintenance, production use, transfer conditions, and any handover cost are agreed before tooling work starts.

When a design fee is part of the proposal, its credit toward a production order is stated in that proposal. The scope, deliverables, and credit conditions are agreed before work begins so there is no ambiguity later.

You receive the engineering deliverables you paid for, subject to the agreed scope. Paid tooling belongs to the agreed owner. Any transfer, storage, or unfinished-work arrangements are handled according to the project agreement.

There is no single minimum across CNC machining, mold projects, investment casting, injection molding, glass, rubber, and silicone. Send the target quantity and process requirements; we will explain the practical economic breakpoints before quoting.

Yes. We define the interfaces, tolerances, finishes, assembly conditions, and acceptance criteria across parts, then manage each specialist process against the same product definition and schedule.

We can review an NDA before receiving sensitive files. Controlled revisions are used for project data, and specialist factories receive only the information needed for their process. If you have specific access, storage, or disclosure requirements, include them in the project scope.

The timeline depends on how complete the requirement is, the validation needed, tooling complexity, specialist process, quantity, and testing. We normally acknowledge the inquiry within one business day and provide a project-specific schedule before paid work starts.
