Glass products factory from China
We supply glass bottles, jars, glassware, lids, and OEM packaging solutions for importers, wholesalers, and food brands.
From reference photo to drawing, 3D model, rendering, prototype and glass mold development, we help turn product ideas into manufacturable glass products.
Step 01
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.

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.

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.
Need support for this step? →Acrylic prototype is closer to glass transparency. Plastic prototype is mainly used for structure and size review.
Design development and 3D prototype sampling usually take about 3-7 days, depending on product complexity, drawing confirmation and sample material.
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.
Different glass products require different machines, molds, finishing methods and packing standards. We help buyers understand the right process before quotation.

Secondary Processing & Finishing
Screen-printed Decal Paper
Standard Decal Paper
Glass cups, drinkware, candle jars, gift glassware, retail glassware and private label projects.
Depends on artwork size, color quantity, paper size and printing method. Screen printing usually requires one film for each color, and each printed color needs drying before the next step.

Before confirming a glass product order, many details can affect cost, production process, packing safety and final delivery. We help buyers check these points before quotation and production.
This section is a practical pre-quotation checklist for glass product buyers, importers, wholesalers and brand teams.
Need support for this step? →Different products may require I.S. machine production, pressed glass, blown glass, borosilicate tube glass or secondary processing. Choosing the wrong process may affect mold cost, MOQ, weight and production stability.
Some shapes look good in drawings or AI concept images, but may be difficult to produce in real glass because of wall thickness, mold opening direction, mouth structure or thermal stress.
Glass unit price is affected by product weight, mold structure, order quantity, finishing process, packing method and quality standard. A lower price is not always safer if packing or defect control is ignored.
Packing should be matched with sales channel. E-commerce orders may need stronger inner protection, while retail or supermarket orders may require reinforced cartons, labels, pallets or FSC-related packing materials.
Before shipment, buyers usually need to check appearance, size, capacity, carton marks, packing method, quantity and loading condition. Third-party inspection can also be arranged when required.
A clear reference photo, size, capacity, weight, quantity, packing requirement and destination help us check the right process and give a more realistic quotation.
