According to a Reuters report on February 25, JDPowder Market Consulting said in a car reliability study released on February 25 that although for most car owners, in-vehicle technology, such as connecting cars to smartphones, and It is cumbersome to issue voice commands, but new technical features will overcome this problem, so that car owners are not bothered by this problem when buying a car.
HONY®PMMA Acrylic is a transparent plastic material with outstanding strength, stiffness, and optical clarity. Acrylic sheet is easy to fabricate, bonds well with adhesives and solvents, and is easy to thermoform. It has superior weathering properties compared to many other transparent plastics.PMMA (PolyMethyl-MetaAcrylate) is an amorphous thermoplastic material with very good optical properties. Acrylic is often used as a glass substitute. Acrylic is hard and stiff but brittle and notch sensitive.
Advantages of Transparent Acrylic Part
Excellent optical clarity, Good Abrasion Resistance, Excellent environmental stability, Good Heat Resistance, Good Chemical Resistance. Flammable but low smoke emission.
Acrylic processing Component Uses
Automotive light covers, Lighting fixtures, Clear Bottles and Container prototypes, Lenses, Shop-fittings, Aircraft glazing, Novelty display cases, Signs, Appliances, Modern furniture, Jewellery items, Medical/Healthcare Applications. PMMA has a good degree of compatibility with human tissues.
Further considerations
PMMA is an economical alternative to Polycarbonate (PC) when extreme strength is not necessary. Common trade names of Acrylic include Plexiglas, Lucite and Perspex. Large and difficult parts can be easily glued.

CNC machining PMMA (Acrylic) Materials with excellent mechanical properties, accuracy and repeatability from metal and plastic. 3-axis & 5-axis CNC milling available.
Because of its transparency, PMMA is often used as an alternative to glass and is popular in the interior design, construction and chemical industries.
It is also regularly used in advertising to fabricate signage, lightboxes and billboards.
Surface Finish
Bead blasting
Bead blasting results in parts with a smooth surface with a matte texture. Used mainly for visual applications and can be followed by other surface treatments.
Painting
Painting the surface of a part improves its aesthetic appearance and can provide brand recognition to consumers. In addition, painting can have a protective effect on parts.
Polishing
Polishing is the process of creating a smooth and shiny surface, either through physical rubbing of the part or by chemical interference. The process produces a surface with significant specular reflection, but in some materials is able to reduce diffuse reflection.
HONY Plastic Manufacturability
Tolerance
- Standard: (+/-) 125 µm -Achievable: (+/-) 100 µm , (+/-) 50 µm
Wall Thickness
- The minimum wall thickness should be at least 1 mm for machined parts. - 2 mm is suggested for better strength and 2.5 mm for a rigid wall.
Pocket depth
- Pocket depth should be up to 3 times the diameter of the end mill
Engraving
- Engraving is preferable to embossing - For the clear, legible text consider fonts such as Arial or Gothic - Design letter strands with a width of at least 2 mm
Internal Radii
- The minimum internal radii possible is 1 mm - In general, internal radii dimensions depend on the depth of pocket being milled
Holes
- Use standard drill bit sizes - Minimum of 1 mm in diameter
Threads
- Use standard metric inserts - Smallest threaded insert possible is M2

The company also said that the appearance and exterior design are still one of the most important indicators when people buy new cars. But if the SUV is not equipped with the latest technology system, 15% of the buyers said they would not buy the car, and this percentage was only 4% last year.
JDPowder's annual report shows that Lexus, Toyota and the recent GM Buick and Chevrolet cars have maintained good ratings, while other car companies have been on the average line for quality control work.
Lexus, the high-end brand of Toyota Motor Corporation, has been ranked first in the report for four consecutive years. On February 24th, the American authoritative magazine Consumer Reports rated Lexus as the best brand in the US market for three consecutive years.
In two reports, GM's car brand Buick has developed well, ranking second in the JDPowder report and becoming the first of the top 10 auto brands in the Consumer Reports category. In the top ten of the JDPowder report, GM Cadillac ranked fourth, and Chevrolet and GMC tied for tenth. A total of 31 car brands are on the list.
Dave Sargent, vice president of JD Power's global automotive research group, said: "GM has been performing well for the past seven consecutive years, improving the average performance of the industry." He also said that Buick's owners are "relatively older" and they It is very likely to go to the retailer to get help with new technologies.
Ford Motor Company continues to innovate in new technologies and has released new technologies such as voice control systems. But its name car brand Ford dropped from 17 last year and 13 in 2013 to 25 this year. Ford still said that its new technology system is easier to operate.
Toyota, Honda and Volkswagen Porsche have taken over half of the top 12 car brands.
In the JD Power report, two brands have consistently scored low and are at the bottom. The penultimate car brand is Fiat Chrysler's brand Fiat, and the penultimate is Land Rover, a brand of India's Tata Motors.
