Reverse design of glass bottle 3D scanning-open mold mass production

Glass products are already an indispensable thing in people’s lives. Glass bottles have many advantages: non-toxic, odorless, transparent, beautiful, good barrier properties, airtight, rich in raw materials, and the main price is low. It can be sterilized at high temperatures and at low temperatures. Storage. Therefore, the use of glass bottles is very wide, so the demand for glass bottles is very large, and the production and processing volume needs to be increased. The production of glass bottles can be expanded by using molds. Due to the various shapes of glass bottles, various types of For the shape of the mold, we need to quickly obtain the shape data of the glass bottle, and then design the shape of the mold based on the 3D virtual data.

Below we use a 3D camera scanner to quickly scan and obtain 3D data of glass bottles:

Customer demand

1. Scanning object: glass bottle

2. Customer needs: quickly obtain the three-dimensional data of the glass bottle, and quickly design the appearance of the glass bottle and design the mold of the glass bottle according to the 3D data of the glass bottle

Problems faced:

Traditional glass bottle sample processing is manual measurement, through the senior benchers to sample bottle manual measurement, with experience in the mold repeatedly modified carved. The production cycle of this method is longer, the precision is low, the surface of the metal mold produced is rough, and the glass bottle surface finish is even higher than the requirements of ceramic wine bottle. The packaging of modern products continues to emerge, with higher and higher requirements on precision and details, and more and more attention to the appearance of bottles. However, the process of redesigning the appearance of bottles is very complicated, which does not meet the needs of rapid development.

Glass bottle 3D scanning reverse design solution -- open mold mass production

The client is a glass bottle manufacturer, and now wants to speed up the design and production of the glass bottle appearance. After a simple communication of needs, the technical engineer of Jingyixun recommended a camera-based 3D scanner. The structured light 3D scanner has industrial-grade accuracy and has a very good degree of reproducibility for scanning the fine lines of the appearance of various bottles. The 3D scanner scans the glass bottle.

1. Preparation

Since the three-dimensional scanner uses optical technology principles to scan objects, objects that reflect, transmit light or absorb light on the surface of the glass bottle need to be surface treated and sprayed with developer

2. Three-dimensional scanning of glass bottles, technical engineers use photo 3D scanner (PTS) to scan to obtain 3D data of glass bottles

3. Obtain 3D data on the surface of glass bottles by using a camera-type 3D scanner, and perform CAD modeling through reverse software to obtain a 3D digital model, which is copied or modified in reverse software to generate a CAD digital model and send it to the mold factory to generate a metal mold , The finished metal mold only needs to modify the features of the fitter master Xiaoxu, which greatly shortens the development cycle.

Highlights of the camera-based 3D scanner used in the glass bottle 3D scanning reverse solution

1. Not restricted by the environment, non-contact scanning

2. Quickly obtain 3D data of the glass bottle, which takes 5 minutes

3. High scanning accuracy

4. Assist 3D software design and drawing

Summary of bottle 3D scanning reverse design solutions

The integration of 3D scanning technology into the glass bottle manufacturing industry is the best way to achieve new product development. It is much faster than traditional design concepts to complete product development, and thus effectively supports the speed of new products responding to the market. It not only helped the mold factory encounter the difficulties in the production process, but also increased the product molding speed to meet the previously incompetent projects. It also shortened the product development cycle for the glass product factory and improved market competitiveness. It also provides a simple way for designers to design more and more novel exotic bottles.
