These crimpers (PWRcrimp, TRIcrimp, Compass Marine, etc.) I believe are sourced through CMI (
https://cmi-mkt.com), which is the intermediary in Taiwan representing various factories in Taiwan and China. So, sure, it's possible and maybe probable they are not
exactly identical but it appears to me the design variants are superficial and the quality will of course depend perhaps on customer requirements. I very much doubt any of them are truly custom or proprietary designs to any one company, not at the price and volume they're selling them.
The Anderson tools (such as their p/n 1309G2 for PP15/30 and 1309G3 for PP45) do not appear to be made by CMI, at least utilizing the same frame design. For one I believe from import documentation that the Anderson tool is manufactured in China (presumably by the contractor Ideal uses, since Anderson is owned by them) and not apparently Taiwan (or at least through a Taiwanese company) like the CMI tools. Also they just don't look the same and the way the crimp pressure is adjusted is different.
