The machine
How it works
Pro-Tocast® is a rotocaster—a rotational casting machine. Mount your mold, pour in resin, and rotate so the material coats the walls. Hollow props, toys, and parts, without print-layer texture. Krimplewips customers will recognize the same design; we have just brought sales home to the shop.
Nearly ten years on the bench. Thousands out in workshops around the world. Built to order, shipped worldwide—shipping calculated at checkout outside the 48 states.
Prop shops, garage kit builders, small studios, surgical teams making prosthetic forms—you bring the resin and the plan; we bring the machine.
Bench scale, built to order—workshop tools, not factory glass rotators or warehouse fulfillment.
For your shop
Workshop price, not factory price
Prop-shop and industrial rotocasters—usually steel or aluminum, built for factory scale—are commonly listed from about $2,500 to $13,000 USD. Pro-Tocast frames are hand-built from wood in our shop, run $139.95–$374.95, and ship worldwide.
We build for benches, garages, and small studios: hollow resin casts, props, and kits—not warehouse rotomolding lines. Every machine is cut, fitted, and tested here. After nearly ten years and thousands shipped, we still haven't found another shop hand-building wood rotocasters at this scale and price—if you know of one, we'd like to hear about them.
- IDM Imagineering — 16″ manual rotocaster (UK) — listed around £2,495
- Mannetron — 3′×4′ rotational casting machine — listed around $12,900
Compare plate size, motor option, and mold weight when you shop. DIY kits and industrial molders are a different category.
For home & bench
Cast what you love
Welcome to your new hobby.
A rotocaster is how you turn a silicone mold into a hollow resin cast—props, keepsakes, figures, and parts with even walls. You make the mold; the machine does the slow, steady rotation so material coats the inside of the cavity.
Keep what matters safe
Mold a treasured vase or heirloom, cast a display copy, and put the original away—same look on the shelf, less worry.
Multiply a favorite
One mold, many pulls—duplicate a figure, toy, or sculpt in different finishes or as gifts.
Build on the bench
Garage kits, cosplay props, and small runs without industrial floor space or glass factory gear.
You will need a silicone mold (and some practice) before your first pour—we ship the rotational casting machine, not the mold kit. Most people start with a simple one-part or two-part mold and grow from there.
The same Pro-Tocast® frames we ship to prop shops, schools, labs, and museums—built to order in our workshop, ready for your bench.
In the shop
How we build
Frames are SPF and white wood. We cut and shape the wood and print the plastic parts here. Motors, hardware, and the rest are chosen for the job and fitted in the shop—this is not an off-the-shelf kit with our name on it. Roughly three to four hours from lumber to a finished machine, each time.
On the bench
The gear ratio took years to get right—smooth rotation you can actually control at bench scale, without fighting the crank.These are workshop tools, not medical devices. You pick your materials and how you use them.
History

Buyers
What people say
A decade of orders through Krimplewips on eBay—and now direct from the same workshop.
- ★★★★★
The product is well built, the delivery was faster than expected and intuitive to assemble & adjust.
- ★★★★★
Works like a champ! It took less than 10 minutes to get unboxed, assembled and spinning. Well thought out and the build is high quality. This is a must have for casting. It'll pay for itself in resin cost savings and no more problems with bubbles and air pockets in your castings. Used Smooth Cast 65D and Smooth Cast 300 and both work well for rotocasting. Great communication and fast shipping!

Pro-tocast Rotocaster WORKS! I bought this for my son so he could cast his original clay design toys. He was up and running almost immediately. Be advised that you should research the process and have some knowledge of the casting process. It is an entry-level piece of equipment so it's perfect for learning to cast, but you must also learn to make molds from silicone from you your own clay sculptures before you use it. It needs very little tweaking right out of the box and you will need about 4 square feet of table space to support it.

I'm new to casting and I've only used this a few times so far, but I'm very happy with it. It needed a little tightening up in spots but NBD. Also shipped and recieved waaaay ahead of schedule, so that was awesome.

Common questions
Rotocasters, molds, and ordering—for home benches, studios, and shops.
- What is a Pro-Tocast rotocaster?
- A hand-built machine that rotates your mold in two axes so resin coats the inside evenly. You get hollow casts—props, toys, parts—without the layer lines you see on a 3D print.
- Is this the same machine Krimplewips sold?
- Yes—same Pro-Tocast® line, same workshop. We now sell direct at pro-tocast.com. If you ordered from Krimplewips before, you are in the right place.
- What sizes do you make?
- 10″ HD manual; 12″ manual and motorized; 18″ manual and motorized; and 30″ manual. Each size is its own frame—not one design stretched to fit.
- Do you ship outside the United States?
- Yes. We build to order and ship worldwide. Free shipping applies to the 48 contiguous US states. Alaska, Hawaii, and international orders: shipping is calculated at checkout when you use Buy now—or email us if the site cannot rate your address.
- What is The Box?
- An adjustable molding box for silicone pours—use it with a rotocaster or on its own. Comes in 10″ and 14″ adjustable sizes.
- How do I order?
- Use Buy now on any product for secure Stripe checkout on pro-tocast.com. You can also shop Banly's on Etsy, eBay, and Amazon, or email us with questions.
- What is your return policy for direct orders?
- Orders placed on pro-tocast.com can be returned within 30 days for a full refund of the purchase price. Contact us at admin@banlys.com before sending anything back. Purchases through Etsy, eBay, or Amazon follow those platforms’ policies.
- What is rotational casting?
- You close a mold, add liquid resin (or similar), and rotate slowly so the material coats the walls. When it cures, you have a hollow part—handy for props, soft goods, and workshop castings.
- I'm new to this—is a Pro-Tocast a good first machine?
- Many buyers are hobbyists and small shops learning as they go. The machine arrives about 95% assembled—you bolt on the base and plates. You should read up on resin casting and how to make or buy a silicone mold before your first pour; we ship the rotocaster, not a complete mold kit.
- What size should I start with at home?
- The 12″ manual is the most popular starting point: a solid bench size, a practical price, and enough room for props, figures, and smaller keepsake molds. Step up to 18″ or motorized frames when your molds outgrow the plate or you cast often enough to want a motor.
- Do I need a silicone mold before I can cast?
- Yes. Rotational casting needs a closed mold cavity—usually silicone you pour around a master (sculpt, print, or an object you are allowed to mold). The rotocaster spins that mold; it does not replace mold-making. Plan on learning a basic one-part or two-part silicone mold, or buying a mold from a maker who sells them.
- Can I cast a copy of a family keepsake or vase?
- People use rotational casting for display copies of treasured objects: mold the piece (when the shape allows), cast a resin duplicate, and store the original safely. Undercuts, very thin details, and fragile heirlooms can be tricky—you need mold-making skill and realistic expectations. This is for your own objects and personal use, not for copying someone else's work or branded goods to sell.
- Can I duplicate my own figures or toys?
- Yes, for personal projects—same mold, many pulls in different paint schemes or as gifts. You make or own the master; we provide the rotation. Do not use a rotocaster to knock off trademarked toys or products for sale.
- Do museums and schools really use these?
- Yes. We ship to prop shops, labs, schools, and institutions as well as home benches—the same workshop-built frames, whether you are casting once a month at home or on a production schedule.
- How does Pro-Tocast compare to professional rotocasters?
- Metal and industrial machines for prop studios are often listed from about $2,500 to $13,000 USD. Pro-Tocast frames are hand-built from wood in our workshop, start under $150, and ship worldwide—built for makers who need real rotational casting without factory-floor pricing.
