The difference between PC prototype and acrylic prototype

The difference between PC prototype and acrylic prototype

Many customers are very puzzled when making transparent prototype. They don’t know what transparent material to choose. They can’t distinguish which PC and Acrylic are better and which one is more suitable for their needs. In order for customers to better understand the advantages and disadvantages between them, the key depends on what kind of performance the customer needs to make. The following describes these two similar materials.

PC resistance to neutral oil, strong acid resistance, not durable, not alkali resistance, to add coating UV.But high temperature resistance, lighting effect is good, PC with high transparency, light, impact resistance, sound insulation, heat insulation, difficult to burn, anti-aging and other characteristics, is a high-tech, comprehensive performance is extremely excellent, energy-saving environmental protection plastic plate.PC can generally withstand high temperature, the temperature is about 120-150 degrees.

What are the advantages of acrylic? The most important thing is the high transparency. After polishing, the transparency can achieve the effect of full transparency. This effect is called plexiglass in the industry. This is unmatched by PC materials. Although PC is also transparent, the effect is not as good as acrylic.


What are the disadvantages of acrylic? Everyone knows that glass is very brittle. Acrylic is a kind of organic glass, so its physical characteristics are also very brittle. The shortcoming of poor toughness causes acrylic to be broken by accident. In the process of making the prototype, this is a key need to avoid, so it can only be replaced with other materials, such as PC.

From the above information, we can see that the advantages and disadvantages of PC and acrylic are: the PC material is generally transparent, the toughness is good, and it can withstand high temperatures. Acrylic has good transparency, poor toughness, and high temperature resistance.

The Difference Between CNC Machining And Urethane Casting

What is cnc machining and urethane casting?

CNC is mean “Computer Numerical Control”.

CNC machining is a technology that machined the parts by removing layers of the material to shape the parts’ structure.

Urethane casting also called vacuum casting and polyurethane casting,is a process that making parts from a mould.It is a low cost way for making low volume plastic parts.


1.The way of machining.
CNC machining is making the parts one by one via CNC machine.
Urethane casting is making a mould according the original parts firstly,and then duplicate parts by the mould.

2.The materials.
Plastic and metal parts can be make by CNC machined.Also,CNC machining is using the pure plastic,such as pure ABS.
But only the plastic parts can be make by urethane casting.Also,Urethane casting is using the mixed plastic,not the pure plastic.Such as similar ABS,not pure ABS.

3.The processing time.
Generally,CNC machining takes more time than urethane casting.

4.The precision.
The precision of CNC machining is 0.01-0.1mm,but the precision of urethane casting is 0.1-0.2mm.We can see that the precision of CNC machining is better.

5.The price.
The price of CNC machining is higher than urethane casting if machined same parts.

How is the quality and safety of plastic molds guaranteed?

Plastic mold processing refers to the plastic molding and plastic blank tool processing, with the upper mold and the next two parts, its basic features are as follows:

(1) high precision machining requirements

A mold is generally composed of die, punch and mold frame, and some may also be more than a split module. So the combination of the upper and lower molds, the combination of the insert and the cavity, the punching between the modules requires a high degree of machining accuracy. Precision precision of the mold is often up to a micron level.


(2) complex surface

Some products such as car covers, aircraft parts, toys, household appliances, the shape of the surface is a combination of a variety of surfaces, so the mold cavity surface is very complex. Some surfaces must be processed mathematically.


(3) small batch

The production of molds is not mass production in batches, and in many cases it often produces only one pay.

(4) process more

Mold processing always used milling, boring, drilling, hinge and tapping and other processes.


(5) repeat production

The use of mold is life-long. When the use of a pair of mold over its life, it is necessary to replace the new mold, so the mold production is often repeatable.

(6) profiling

Mold production sometimes no pattern, no data, but also according to the physical copy processing. This requires high imitation precision, no deformation.


(7) mold material is excellent, high hardness

The main material of the mold is made of high quality alloy steel, especially the high life mold, often used Crl2, CrWMn and other lignocellitic steel. This kind of steel from rough forging, processing to heat treatment are strict requirements. So the preparation of processing technology can not be ignored, heat treatment deformation is also the need to seriously deal with the problem.

Understand the basic characteristics of plastic mold processing, in the selection of machine tools to meet the processing requirements as much as possible. Such as the function of the CNC system to be strong, high precision machine, rigid, thermal stability is better, with copy function. Official website: http: //
