2Pcs Extra Large Epoxy Resin Table Molds 19x11x3 & 15.7x9.8x3 in

In this review the focus is on a practical, no-frills pair of large epoxy molds made for makers who need deep, repeatable casts. The set includes two rigid PP molds sized 19.6x11.8x3 in and 15.7x9.8x3 in plus a rubber mallet, and the single biggest reason to consider them is their depth and reinforced edges that let you pour thicker river table pieces, serving trays or cutting boards without worrying about leaks. This review covers ease of use, durability, and whether the harder PP material is a fit for frequent resin work.

Key Features

• Two sizes included: The pair of molds covers large and medium rectangle needs so you can mix board sizes for tables, trays, and panels.
• 3 in depth: The substantial depth makes it practical to pour thicker river table pours or layered art without multiple partial pours.
• Rigid PP construction: The hard polyproylene body is reinforced to resist deformation and stands up to repeated use better than thin disposable molds.
• Seal-free design: Mold halves have no welds or rough gaps so you do not need extra silicone or sealing to prevent resin leaks.
• Smooth inner surface and draft angle: The slightly outward-tilted sides and slick interior reduce suction and make demolding easier once resin is fully cured.
• Includes rubber mallet: The supplied mallet helps tap and encourage release without risking damage to your cured piece.

Who It's For

This set is aimed at hobbyists and small makers focused on larger epoxy projects like serving trays, charcuterie boards, shallow coffee or side table tops, and art panels who want a reusable, robust mold set without the softness of silicone. The depth and reinforced edges make it particularly suited to pouring epoxy around wood inserts for river table effects.

Makers seeking perfectly flat, high-end mold finishes or those who prefer soft silicone molds for extremely delicate demolds may want to look elsewhere. Also, buyers who expect a softer, silicone feel should note these are hard PP molds and some users report slight curvature or flatness concerns on finished pieces if the substrate is not fully supported during curing.

Pros & Cons

Pros

• Durable, thick PP construction that resists punctures and repeated use.
• Two complementary sizes in one package cover multiple project types.
• Seal-free manufacturing reduces prep time and worry about seams leaking.
• Easy demold process aided by the draft angle and included mallet.

Cons

• Rigid plastic material may produce slight flatness or edge curvature on some casts compared with premium silicone molds.
• Not silicone; some users prefer softer molds for delicate or highly detailed demolding.

Our Verdict

For makers who need dependable, deep, reusable molds for larger epoxy projects this set offers strong value: the two sizes, thick reinforced edges and seal-free PP construction make it a durable choice for trays, boards and small table tops. Those who require ultra-soft silicone for maximum finesse should consider alternatives, but for repeatable, heavier pours these molds deliver reliable performance at a practical price.

Frequently Asked Questions

Are these molds silicone?
No, the molds are made of hard polypropylene (PP) rather than silicone, which makes them rigid and reinforced.

Will resin leak from seams?
The molds are manufactured seal-free with no welds or rough gaps, so they are designed to prevent leaking without additional sealing.

How do you demold large cured pieces?
Clean and release the inside, allow full cure, then use the included rubber mallet to tap sides and bottom while flipping the mold to ease release.
