Design, manufacture and deliver.
Explore how a glass product moves from an initial reference through technical development, manufacturing, decoration, inspection, packing and shipment. The content below comes directly from Yubai Glass’s existing workflow and process guides.
OEM Design & Sampling Workflow
From reference photo to drawing, 3D model, rendering, prototype and glass mold development, we help retail buyers, wholesalers and OEM glass packaging projects turn product ideas into manufacturable glass products for China-based supply.
This OEM workflow supports buyers looking for a large scale glass manufacturer China, OEM glass packaging supplier USA retail chain support and wholesale glass bottle factory China capability before mold development.
Review Factory Capability →Step 01
Concept Reference
Customer sends a reference photo, concept image, sample picture or target style. We first check product shape, glass process, size possibility and mold direction.
Customers can start with a reference photo, sample picture, hand sketch or product idea. We check shape, glass process, size possibility and mold direction before development.
Discuss Your Custom Project →Step 02
Technical Drawing
We convert the idea into a technical drawing with size marking, capacity direction, mouth details and key structure information for review.
Customers can start with a reference photo, sample picture, hand sketch or product idea. We check shape, glass process, size possibility and mold direction before development.
Discuss Your Custom Project →Step 03
3D Modeling
After drawing confirmation, we create a 3D model to review product structure, proportion and manufacturability before sampling.
Customers can start with a reference photo, sample picture, hand sketch or product idea. We check shape, glass process, size possibility and mold direction before development.
Discuss Your Custom Project →Step 04
Revision & Confirmation
We discuss the drawing, model or sample with the customer, adjust details when needed, and confirm the final direction before mold development.
Customers can start with a reference photo, sample picture, hand sketch or product idea. We check shape, glass process, size possibility and mold direction before development.
Discuss Your Custom Project →Step 05
Glass Mold Development
We use mold breakdown images to help customers understand how glass molds are developed, assembled and prepared before trial production.
Customers can start with a reference photo, sample picture, hand sketch or product idea. We check shape, glass process, size possibility and mold direction before development.
Discuss Your Custom Project →Step 06
Patent Certificate
For selected custom projects, patent application or certificate materials can support product protection and buyer confidence during development.
Customers can start with a reference photo, sample picture, hand sketch or product idea. We check shape, glass process, size possibility and mold direction before development.
Discuss Your Custom Project →3D Prototype Options
Acrylic prototype is closer to glass transparency. Plastic prototype is mainly used for structure and size review.
Design & 3D Sampling Time
Design development and 3D prototype sampling usually take about 3-7 days, depending on product complexity, drawing confirmation and sample material.
From Prototype to Glass Mold
After prototype approval, we choose the suitable glass forming process and develop the mold. Glass molds are commonly made from cast iron or other suitable mold materials for high-temperature resistance and heat dissipation.
