Plastic weed grinders are typically made of acrylic (a type of plastic) and have the appeal of being significantly cheaper in cost - yet this does not come without penalty!
Most plastic weed grinders come as a two piece or three piece grinder (as opposed to four-piece grinders) and generally plastic does not have the same crushing strength as a metal grinder. Often times plastic grinders have fewer and less durable teeth which may lead to teeth breaking off during the crushing.
Not only may the cone teeth break off - but generally plastic is ineffective at grinding denser buds. The material may get clogged in between the grinder and the grinder may eventually lose its functionality in grinding overtime - resulting in more difficult if not impossible twisting.
Don't get us wrong. A plastic will grind - Just not as well!
- We definitely Would definitely recommend a plastic grinder for the Price.
- We definitely Would NOT recommend a plastic grinder for the Quality.
We would rather recommend a Metal Grinder for a higher-quality grind.
Cheers and Happy Grinding :)
