xiehe model

The rapid prototype can be said to be deeply loved and welcomed by the public, and it has the function of avoiding a lot of losses. So do you know what are the characteristics of the hand model making process? Next, the Xiehe prototype processing factory will give you a brief introduction.

The technical characteristics of hand model:

When the drawing is completed or a new product design is completed, that is, before it is put on the market, the first thing you want to know is the market benefit of this product; or whether there is any difference between the design drawing and the actual product or whether it is reasonable, etc. At this time, it is recommended You first make a hand model. Profoundly speaking, a prototype is to make one or more models based on product design drawings or structural drawings without opening a mold, to check the appearance or functional model of structural rationality.

Prototype classification:

1. Manual prototype: it is mainly an early prototype, and this method is rarely used now, because it is mainly manufactured by hand, and the size and appearance are difficult to meet the requirements, so this method is rarely used at present.

2. CNC prototype: It is mainly completed by CNC machine tools, so it can be divided into laser rapid prototyping (RP) prototype and CNC machining center

(CNC) prototype. Advantages of RP prototype: fast speed, mainly formed by stacking technology, so the prototype is generally rough; in addition, products with too thin wall thickness cannot be manufactured by this method.

Advantages of CNC prototyping: accurate, high-quality appearance, such as after spraying and silk screen printing on the surface, it is almost the same as the real product. It can be molded directly on plastic, which is more in line with product requirements, so CNC prototypes will become the mainstream of the prototype manufacturing industry.

Prototypes can be divided into plastic prototypes and metal prototypes according to the materials used in manufacturing:

1. Plastic prototype: its raw material is mainly ABS or other flexible plastics, such as some popular but newly developed products in the market, such as functional telephones, display casings, game consoles, etc.

2. Metal prototypes: the raw materials are mainly aluminum-magnesium alloys or others, and are mainly used for some high-end prototypes, such as notebook computers, CD players, MP3, MP4 players and other home appliances.

3. Usually, some expensive products such as mobile phones and digital cameras generally need to make model machines before they are put on the market, that is, the so-called mobile phone model machines, camera model machines, etc. The mold processing is generally as follows:

A. Keep the appearance unchanged on the basis of the original 3D drawings of the mobile phone, and then modify the external structure to the most complex structure that meets the customer's requirements.

B. According to the appearance of the real machine, use the most complicated process that can be produced in large quantities, such as silk screen printing, oil injection, electroplating, etc., to imitate the appearance of the real machine, with a simulation degree of more than 80%. Some effects on the real machine, such as metal wire drawing, IMD process, etc. The cost is high, and it is generally completed by hot stamping, silk screen mirror silver and other common processes, which can achieve the purpose of reducing costs. For mobile phone model machines, digital camera model machines, etc., if customers have no special requirements, ordinary materials such as 718 for cores can be used.

The above content is the technical characteristics of rapid prototype making introduced by Xiehe rapid prototype processing manufacturers, hoping to increase everyone's understanding of rapid prototype models. If there is a customer who wants to customize the rapid prototype of the car light, please call the Xiehe rapid prototype processing factory, and we will serve you wholeheartedly.
