    They have been off the market for two decades. They felt different, which for some meant great. To my knowledge there was only one manufacturer. Their racquets still have many fanatics.

    Is there a niche for a modern injection molded racket?

    Please see the poll and check the boxes that apply to you.
    Feel free to suggest options if you don't find the relevant one.

    NB: The Prince Vortex was NOT injection molded, though it did incorporate thermoplastic components

    NB2: I didn't realize that the poll allows only one entry per user. Please pick the most important feature and add a reply with the others, I'll tally the results.

    i voted for 92, i think that headsize is more relavant today.
    the balance isn´t as important, since i can customize. in this regard it would be nice to have a racquet that is light enough that you can put some lead on it.
    Made in USA is nice as long as the quality control is better than Made in China. not everything that is made in China is necessarily poor qc. the western markets are just flooded with cheap products from China

    I don't seem to be able to click multiple selections. Can you fix?

    I'd like 7 HL, 92 sqin.

    Idealy, I'd realy like to see it in 95-98 sqin, 4 HL and at least 20g, lighter then original. That would leave the space to tune to your desired weight and balance.

    Does injection molded mean that the racket is "solid" unlike the one today which are hollow inside the carbon fiber tube?

    No....
    Here are sections cut from the Max 200G to show the internal pillars that you can only have with a Injection Molded Frame.

    A real piece of art how Dunlop manufactured these racquets. Here is a layman's explanation of the Injection Molded Process works. First there is a casting of a low melting point alloy core. The alloy core is then put in the injection molding machine. A Compound of GRAPHITE and NYLON is Melted and then injected around the alloy core. Once the graphite and Nylon is cooled the Alloy core is heated up so it melts and then poured out of the frame. This leaves individual string holes that have pillars inside the frame. There are no holes drilled in these injection molded frames by Dunlop.

    If you can figure out away to get a IMF that is 95sq.in, 22mm wide beam width, and still being about 12oz strung without breaking you will hit a home run!!!!!!!

    vsbabolat beat me to it. I only have to add that the frame is still hollow and that is because of structural reasons. The same way a steel tube is more rigid than a steel rod of the same mass, a hollow frame will have better properties than a solid frame.

    12oz strung is not something I would attempt. 95 sq. in may be feasible. Given that the 84 has a sweet spot comparable to a modern 90, do you really want to move through the air a bigger hoop? The 500i is 95 sq in and takes a lot to handle. A nice stick though once you get the hang of it.

    The Max500i was also a absolute log. The ones I had were heavy about 13+oz.

    There are many backhand shots that I can only hit with a Max 200G and to this day the way it destroys the ball on the forehand (very flat) in a way that for me has been impossible to duplicate with any other frame. Also those rackets were very flexible. An update would need an RA of at least 50 but no higher than 57. A special kind of control and power combo with that frame.

    I feel it would be cost prohibitive to use the same hotmelt metal used in the originals.

    Scary high mould costs for the casting and overmoulding. I think the last set I used at Dunlop cost around £200,000

    And that was, of course, 20 years ago. We would love to learn from your experience.

    Price?
    I know, if you have to ask you can't afford it.
