What is PLA?
PLA plastic or polylactic acid is a vegetable-based plastic material, which commonly uses cornstarch as a raw material. This material is a thermoplastic aliphatic polyester and it is the primary natural raw material used in 3D printing. PLA is a fully biodegradable thermoplastic polymer consisting of renewable raw materials.
Among all 3D printing materials, PLA is part of the most popular materials used for additive manufacturing.

PLA Plastic
In plastic injection, this material is used to make packaging, primarily for the food industry as a substitute for fossil fuel-derived plastics, because the material is appropriate for food contact.

What about PLA mechanical properties?
In contrast, PLA will be less durable, more fragile, and more sensitive to heat than ABS.
PLA has a glass transition temperature of 65 °C and a melting temperature of 178 °C. PLA is not the most heat resistant material, this is why it is particularly suitable for decorative objects with no mechanical constraints.
Using polyamide powder sintering technology will provide even better results from a mechanical point of view.

What are the advantages of PLA?
PLA material has numerous advantages, and that is precisely why this is the most used plastic material for desktop 3D printers. PLA filaments come in a lot of different shades, styles, that can fit many different applications.

What are the applications of PLA?
It comes in the form of wire on a spool, which is fed into the extruder head where the plastic is melted and deposited into fine drops on the printing tray. This material is translucent in its natural form, but spools of dyed filament can be used to make objects in different colors.
When cooling, this material contracts less than ABS, which gives it good geometric stability during the manufacturing process.
PLA can be useful for your product development, as this material can be used for rapid prototyping. But the main applications for this material are toys, figurines, non-functional prototypes, etc.

PLA Pulverizer Grinder
PLA pulverizer of the PNMF series is available with disc diameter from 300 to 800 mm. These plastic pulverizer machines are high-speed, precision grinders for the processing of medium-hard, impact resistant and friable materials. The material to be pulverized is introduced through the center of a vertically fixed grinding disc which is mounted concentrically with an identical high speed rotating disc. Centrifugal force carries the material through the grinding area and the resulting powder is collected with a blower and cyclone system. Depending on the application the machines can be equipped with one-piece grinding discs or grinding segments.

The plastic pulverizer machine is mainly composed of an electric motor, disc type blade, feeding fan, vibrating sieve, dust removing system, etc.
According to the customer’s needs, you can choose some accessories, such as a converter, vacuum loader, screw loader, magnetic net, metal separator, chiller, pulse dust collector, metering and weighing packaging machine, etc.
