Custom Plastic Ruler Injection Mold

The Sea Monkey Project design and manufacture custom plastic injection molds for groups around the world. We specialize in creating premium molds for fun and functional products, like these colorful, pocket-sized rulers, branded with your logo and message of sustainability. If you're a school, makerspace, or an educational center focused on engaging youth in plastic upcycling, this is a great mold investment to consider.

Our rulers are ~155x30x5mm, and use 10 to 20g of upcycled plastic. We typically recommend 2-parts-per-injection ruler molds, as pictured above, but we can also make 1-part-per-injection molds at a reduced cost if your budget is restricted.

Since 2018, we’ve placed 285+ machines in 33 countries, including 115+ machines located in community project sites here in Malaysia. All of our machine sets are customizable to suit the specific needs of our clients and partners, and supported by optional education, start-up, and training packages, available both on-site and on-line. We have the knowledge and experience to help you scale both the quality and quantity of your plastic production, having developed our own network of community project sites, and manufactured 185,000+ products from 100% upcycled plastic using our plastic recycling machine sets.
