PC Materials Finishing:Various Processing Methods For Finishing PC Pellets

Various methods are employed to finish PC pellets into finished products,and among them,injection molding is the most prevalent.

Injection Molding

Injection molding involves heating and melting of PC pellets,injecting them into a mold,and afterward cooling them to form the final product.It is highly effective and can mass-produce high-tech products.

JS's engineering practice has shown that to obtain high-quality PC injection molding parts, the key lies in the precise coordination and control of melt temperature, injection speed, and mold temperature, which directly determines the magnitude of internal stress and the dimensional stability and optical performance of the final product.

Laser Cutting

Using a high-energy laser beam to cut PC sheets,it features high accuracy,smooth cutting,and zero mechanical stress.It can be used for processing high-precision,complex products such as decorative panels and electronic protective covers.

Power and speed have to be adjusted according to sheet thickness.The thicker the sheets,the higher power and slower speed.It requires no mold,and therefore it is suitable for small-batch,high-variety production.

CNC Machining

Machine tools controlled by the computer drill and mill PC sheets to high precision with good repeatability.It is suited for complex,high-precision products such as precision instrument casings and mechanical transmission components.The right tooling and parameters must be selected in order to avoid sticking of tools and surface roughness.High-precision hole and thread cutting can also be obtained.

3D Printing

Additive manufacturing technology builds PC material layer by layer without mold demand.It is used for R&D prototyping and small-volume customization.

Special PC filament or powder is required.The product performance and precision are enhanced,but the process speed is reduced and the strength is less than injection molded products.Currently,its application is growing in areas such as customized phone cases and glasses frames.

Now that we know about PC processing methods,let's put PC and glass against one another to understand which one is the"King of Drop Resistance."

PC vs.Glass:Which One Is Truly The"King Of Drop Resistance"?

Glass is clear and heat-resistant,but brittle.PC is clear and incredibly tough as well.The two are very different,though,when it comes to impact strength,density,and light transmission.The relative values are presented in the table below,clearly indicating which offers superior drop resistance:

Performance Indicators	PC(Polycarbonate)	Glass	Advantages of PC
Impact Strength(kJ/m²)	60-80	About 1	The anti drop performance far exceeds that of glass, and the risk of damage is extremely low.
Density(g/cm³)	1.20	2.50	More lightweight, which can reduce transportation, installation, and usage costs.
Light Transmittance(%)	90-92	90-95	The comparable light transmittance makes PC more suitable for scenarios such as children's rooms and sports venues.
Temperature Difference Resistance(°C)	Resists between-40°C and 120°C.	Easily shatters with extreme changes in temperature.	Good temperature resistance.
Weight(for the same volume)	Lighter	Heavier	It can reduce the burden on the supporting structure.

In terms of impact strength, the impact strength of PC is 60-80 times that of glass. According to JS's drop ball impact test data, PC boards of the same thickness can maintain structural integrity even when subjected to impact energy far exceeding the glass limit, while glass is bound to break. Excellent drop resistance makes PC the preferred choice for high safety scenarios.

Clearly,PC is the undisputed "king of drop resistance" with advantages in terms of density and thermal resistance.It is also taking over for glass in applications such as building skylights and auto windows.

FAQs

Q1:Will PC material yellow after extended sun exposure?

Plain PC material will yellow with extended sun exposure.However,PC material with anti-UV additives resists UV degradation quite vigorously.For example,outdoor smart doorbell housings built with such materials can maintain high transparency after six months of outdoor exposure.

Q2:When making small lots of PC components,is CNC machining or 3D printing more suitable?

You get to decide.If you require high precision(within±0.1mm tolerance)and rapid checking of design,CNC machining is employed,which permits prototypes in three days.If the part is complex and doesn't require radical accuracy,3D printing doesn't require the employment of molds and is suitable for small-volume customization,but is slower and less durable than components CNC machined.

Q3:When injection molding one-off PC injection molding parts,will mold cost affect the overall injection molding price?

Yes.Mold expense is a significant initial cost in custom injection molding production.The larger the size of the part and the more complex the design,the more difficult and expensive the mold production is,which then raises the initial injection molding price.However as production lots become larger,the cost per unit of the mold decreases,leading to a lower total cost.

Q4:Why does my PC component border become white during laser cutting?

This is typically caused by thermal stress.Heat input can be reduced by optimizing laser cutting parameters such as power,speed,and air pressure.Skilled service providers are able to achieve almost crystal-clear cut edges through process control.
