PEN KIT MALL Four-Cavity Resin Mold For Pen Blanks
This silicone mold is designed to shape resin into pen blanks with four equal cavities in one pour. Each cavity measures roughly 1 3/8 inches wide by 5 1/8 inches long and 1 3/8 inches deep, enabling the creation of comfortably sized blanks suitable for many popular pen kits. The mold’s design targets practicality: it is advertised as not requiring a separate mold release, which can simplify workflow and reduce prep time in busy workshops. The oversized cavities help accommodate a range of resin blends and embed materials. The reusable silicone construction minimizes sticking and makes demolding straightforward after curing.
Key considerations include the four-cavity layout, which supports batch production and consistent blank dimensions, and the emphasis on compatibility with handle or duck-call blanks given the cavity size. Users should still verify their resin system’s cure profile and ensure their resin mixture achieves a smooth surface before demolding. While listings promote no release agent as optional, practitioners who use strongly pigmented resins should consider light lubrication or a wipe-down to speed release and prevent surface imperfections during demolding.
Peachtree Color Splash Acrylic Resin Pen Blank
The Color Splash line from Peachtree Woodworking Supply delivers acrylic resin pen blanks with vibrant, variegated color patterns. The blanks measure 3/4 inch by 3/4 inch by 5 inches, making them compatible with a wide range of common pen kits. The blend of colors creates a dynamic look when turned and finished, appealing to crafters seeking eye-catching pens. Acrylic blanks like these are valued for their ready-to-turn simplicity—often requiring minimal waxes or finishes to achieve a glossy, smooth surface. Users typically pair these blanks with high-grit sanding and CA glue for secure turning and a durable finish.
From a process perspective, the Color Splash blanks are favored for their straightforward workflow: select a color pattern, mount in a chuck, and finish with standard turning and polishing steps. The caveats include potential variations in color patterns from blank to blank, since colors are applied in blends rather than a single uniform color. For best results, test fit and balance on a few units before committing a batch run and consider protecting the blank edges during initial turning to minimize tear-out on highly-pigmented resins.
Woodriver Quad-Cavity Silicone Mold
This mold is built to cast four oversized pen blanks at once, with a modular approach that supports production efficiency. The quad cavity design accommodates 1″ x 1″ x 6″ blanks, ideal for larger pen kits that call for substantial turning stock. The mold integrates 3mm fillets to aid release and reduces warping risk, while rounded corners improve turning safety and reduce corner tear-out. The silicone material is reusable and resistant to staining from many resin blends, which is helpful for makers who experiment with multiple color combinations or embed materials such as fragments or metallic flakes.
Manufacturers emphasize ease of release and consistent blank geometry, but users should allow full cure time in a stable environment to avoid deformation. Proper degassing and clamping during curing can help maintain flat blank faces. While silicone molds are forgiving, practitioners should inspect the mold seams before pouring to ensure there are no minor gaps that could mar the blank’s surface. Regular cleaning with mild soap and water will extend mold life and maintain surface fidelity between pours.
PEN KIT MALL Ten Assorted Acrylic Pen Blanks
This assortment from Pen Kit Mall provides ten acrylic pen blanks in a mix of colors and designs, designed for turning into custom pens. Each blank measures 5/8 by 5/8 by 5 inches, offering a compact yet versatile size for a variety of pen bodies. The listing notes that blanks come assorted, with a mix of solids and patterns, and are ready to turn without additional prep work. For makers who want a quick-start option or project diversification, a ready-to-turn pack like this reduces the need to source individual colors and patterns.
When selecting these blanks, consider the balance between color variety and the desired final aesthetic. Depending on the resin formulation and color depth, some blanks may present more visual drama when finished with a glossy CA or epoxy finish. Since the pack is assorted, it’s wise to dedicate a small test batch first to evaluate how the colors lighten or darken after sanding and polishing. Store unused blanks in a cool, dry place to preserve color integrity over time.
Acrylic Pen Blanks Ten-Pack Mix One
From Crooked Mill Woodworking, this ten-pack of acrylic pen blanks offers blanks that are approximately 5 inches long and 3/4 inch in both width and height. The mix-one set is designed to provide a broad spectrum of looks, aligning with common pen kits while enabling creative color stories. The assortment approach helps makers experiment with patterning, transparency, and layering, which can yield distinctive results when turned and finished. Acrylic blanks like these typically deliver a clean, bright surface that responds well to polishing and CA finishes.
Consider this option if you want a straightforward, bulk supply of blanks with reliable dimensions. As with any mixed-color pack, you may see variability between blanks, so it’s prudent to audition a few pieces to calibrate your turning approach and finish schedule. Proper storage away from prolonged heat and direct sunlight will help prevent color fading or edge cracking over time.
Buying Guide
Resin Type And Application
Resins used for pen blanks generally fall into two broad categories: epoxy-based resins and acrylic blanks. Epoxies are popular for deep, glass-like color with bold inclusions or embedded materials. Acrylic blanks are valued for bright color and a predictable, easy-to-finish surface. Mold-based resin components (silicone molds) focus on shaping resin into pen blanks, while ready-to-turn blanks give you a head start by providing a finished form. Decide whether you want to cast blanks yourself or work with pre-shaped inserts, based on your workflow and turning preferences.
Ease Of Use And Workflow
For beginners, resin blanks or pre-cut acrylic blanks that require minimal setup can accelerate learning and reduce trial-and-error time. Molds that do not require mold release or are known for easy demolding can simplify the casting process. If you enjoy batch turning, a quad- or multi-cavity mold lets you produce multiple blanks in a single pour, improving throughput. Always follow resin manufacturer guidelines for mixing, degassing, curing temperature, and humidity to ensure consistent results.
Color, Pattern, And Finish
Colorful blanks and molds open creative possibilities. Acrylic blanks often yield vibrant, consistent color that polishes to a glass-like shine. Molds enable resin designers to embed inclusions or layered colors for depth. When evaluating options, consider how color will look after turning, sanding, and polishing. Some resins require additional waxes or CA finishes to achieve maximum gloss, while others are designed to shine with minimal post-processing.
Compatibility With Pen Kits
Match blank dimensions to your preferred pen kit. Common blank sizes—such as 5 inches long by 3/4 inches thick—fit many standard kits, but always verify length, wall thickness, and head-cap fit. For larger or custom pen styles, look for oversized blanks or molds with cavity dimensions that align with your intended nib, cap, and body. If you use nibs with extended threads or unusual diameter, consider blanks that provide extra material or thicker walls to ensure a clean finish after turning and trimming.
Durability, Safety, And Maintenance
Resin blanks should offer durability under turning pressure. Epoxy and acrylic blends can vary in toughness and resistance to tear-out. Wear proper safety gear when sanding resins, as fine dust can irritate airways; use a dust mask and proper ventilation. Cleaning and storing molds or blanks properly extends life: rinse silicone molds with mild soap, store blanks away from direct sunlight to minimize color fading, and keep resin shop areas free of humidity fluctuations that could affect curing times.
Value And Availability
Consider the total cost per blank when evaluating value. Molds and blank packs from reputable brands may carry a premium, but they often deliver more consistent results and a smoother turning experience, potentially reducing waste. Availability can vary by season, so it’s helpful to stock up on preferred options when they’re in stock. If you’re building a diverse collection, a mix of molds and assorted blanks can provide broad creative flexibility without needing multiple suppliers.
Bottom Line — Choosing The Right Option
For beginners seeking straightforward, reliable results, ready-to-turn acrylic blanks and well-reviewed mold kits offer a good starting point. Intermediate and advanced turners may enjoy the flexibility of multi-cavity molds for batch production, or the depth of color available in resin blends. The best choice depends on your turning cadence, desired aesthetic, and how much preparatory time you’re willing to invest. Always verify that the blanks align with your pen kits and follow safety and curing guidelines to achieve the best finish.
