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.

What is sheet metal prototype processing?

/in , /by

Sheet metal processing refers to the processing technology of sheet metal, and sheet metal parts are thin metal parts.The sheet metal process is an induction cold-working hand plate manufacturing process for metal sheets (usually below 6mm), including shearing, punching/cutting/compounding, folding, welding, riveting, splicing, forming (such as car body), etc.It is plastically deformed by craftsmanship or die stamping to form the desired shape and size, and can be further welded or a small amount of mechanical processing to form more complex parts, such as chimneys, iron stoves, and car shells commonly used in life.The obvious feature is the same thickness of the same part.The three most important processes of sheet metal processing are shearing, punching/cutting, and folding.

The surface finish of prototypes–laser engraving

/in , , /by

Laser engraving, also called laser marking, which is a process that uses optical principles for surface finish.This process is usually used on the keys of mobile phones and electronic dictionaries.Laser engraving is to engrave the traces of chemical and physical changes of the surface layer material by the light energy of the laser beam, or burn off some materials by the light energy, and display the required etched graphics and text.

And According to different engraving methods, it can be divided into dot matrix engraving and vector cutting.Vector cutting is different from dot matrix engraving. Vector cutting is performed on the outline of the text. This mode is usually used to cut through on wood, paper, acrylic and other materials, and can also be used to mark on the surface of a variety of materials.

Vacuum casting ABS UL94 V0 prototype

The vacuum casting greatly reduces the development cost, cycle and risk of the product. More than 20 pieces of the same product can be made using a silicone mold. This makes the vacuum mold become one of the commonly used prototype manufacturing methods in industrial production.

The vacuum mold refers to the use of the original prototype to make a silicone mold in a vacuum state, and use PU, transparent PU, POM-like, ABS materials for casting in a vacuum state,
So as to clone the same copy as the original prototype.
There are many materials for vacuum casting, and it can also be made of fireproof materials. Can withstand a high temperature of 180 degrees. So how do we produce fire-resistant ABS prototypes?

1,The first is to check the drawings to evaluate the production. Because the shrinkage rate of the vacuum casting is relatively large.In order to ensure the accuracy of the parts, the size of the parts needs to be enlarged according to the probability of shrinkage before production.

2,3D-Printed master mold.

3Make silicone mold.

4,Put the liquid fireproof ABS into the mold and take out the product after cooling.

 

 

 

 

Sandblasting surface finish of prototype model

/in , /by

The prototype of the newly processed prototype model generally requires surface post-finish,and the sandblasting is one of the surface finish processes.

Through the surface finish of sandblasting, the tiny burrs on the surface of the parts can be cleaned, and the surface of the parts is smoother, more beautiful and more precise.And it can greatly improve the mechanical properties of the prototype surface.Therefore, the fatigue resistance of the parts is improved, the adhesion between the parts and the coating is increased, the durability of the coating film is also extended, and it is also conducive to the leveling and decoration of the coating.

The E-make team has more than 30 years of combined experience in prototype machining, CNC manufacturing, vacuum casting service.And has a high-level technological group of 25 peoples.The processing quality of the rapid manufacturing is stable, the processing precision is high, and the appearance is exquisite.

The processing of vacuum casting prototype

 

We usually use CNC maching to processing prototype ,but the CNC tooling is hard , can only  process hard material.So if customer need to make rubber product ,we will not be able to use CNC machining .In that time ,we will use vacuum casting to process.vacuum casting is the best way to make rubber product in small quantity.So how vacuum casting to process a prototype?

1,programming.

2,make a mold.

3,Pour the liquid soft rubber material into the mold and take it out after cooling.

4,surface finish:

If those rubber product need to do color,there have two way to make color.one is painting after the product out of mold .Another is the color and the product out of mold together.This mean mix the color powder andrubber materials required by the customer into the mold, and take them out after cooling.

At this time, the product comes with its own color when it comes out of the mold. But the price will be more expensive than painting.

The surface of the vacuum casting product is smooth, and generally does not need manual processing. Which can save manual processing time.

If you have rubber products to make, please contact E-make. We are a rapid prototyping manufacturer in China, with over 10 years of experience in CNC,3D printing, vacuum casting and injection molding die-casting prototypes. We can quickly and cheaply produce high quality parts and prototype for you.
