Flexible Sampling Frameworks
Whether you need to evaluate our raw material capabilities immediately or require a bespoke prototype engineered to your exact CAD specifications, we offer transparent, tiered sampling solutions designed to accommodate varying stages of the product development lifecycle.
Standard Material & Stock Samples
Ideal for initial physical evaluation, our standard samples consist of existing catalog items, material swatches, and standardized test plaques. This allows your engineering team to physically interact with our silicone formulations, testing tensile strength, elongation at break, and evaluating surface finish options (matte, glossy, or textured).
Standard samples: Free of charge; customer pays shipping cost. Delivery 3–7 days.
We dispatch these via trusted international couriers (DHL, FedEx, UPS) ensuring you receive the materials promptly to keep your R&D timeline on track.
Custom Engineered Prototypes
When standard swatches are insufficient, we transition to custom rapid prototyping. Utilizing prototype aluminum or soft steel tooling, we can mold your exact geometry. This process is crucial for verifying complex undercuts, overmolding adhesion, and precise dimensional tolerances before committing to expensive multi-cavity hardened steel production molds.
Custom samples: Special size, color, logo, structure, hardness. Charging sampling fee; deductible in mass orders.
This financially risk-free approach means your initial R&D investment is fully credited towards your eventual manufacturing costs, establishing a true partnership model.
Comprehensive Sample Range Across Industries
Silicone's versatility—characterized by extreme temperature resistance, chemical inertness, and biocompatibility—makes it the material of choice across diverse sectors. Our specialized engineering cells cater to the unique regulatory and functional requirements of each industry. Sample range: Medical silicone, baby products, pet products, industrial seals, keypads, LSR parts.
Medical Grade Silicone
Developing medical devices requires uncompromising safety. Our medical samples utilize FDA-approved, Class VI, and ISO 10993 compliant raw materials. Produced in cleanroom environments, these prototypes are ready for rigorous sterilization testing (autoclave, gamma, EtO) and biocompatibility validation for surgical instruments, fluid management tubes, and wearable health monitors.
Baby & Infant Products
Safety and durability are paramount for infant care. We provide samples for pacifiers, teething toys, and feeding accessories using 100% food-grade, BPA-free, and phthalate-free silicone complying with LFGB and FDA standards. Our samples allow you to test tear strength, bite resistance, and ergonomic safety before launching consumer-facing infant product lines.
Industrial Seals & Gaskets
Industrial applications demand resilience under extreme conditions. Request samples of custom O-rings, complex gaskets, and vibration dampeners. We formulate samples to withstand extreme thermal cycling (-60°C to +250°C), UV exposure, ozone degradation, and specific chemical resistance requirements, ensuring hermetic sealing in automotive, aerospace, and heavy machinery.
Electronic Keypads
Tactile feedback is critical for user interface design. Our custom keypad samples allow you to test actuation force, snap ratio, and conductive carbon pill resistance. We provide prototypes with various surface treatments including PU coating, epoxy coating, and laser etching for backlighting, ensuring optimal performance for consumer electronics and industrial controls.
Liquid Silicone Rubber (LSR)
For high-precision, high-volume manufacturing, LSR injection molding is superior. We offer LSR prototyping to validate complex geometries, micro-molding features, and optical clarity. LSR samples demonstrate the flashless, waste-free potential of your design, utilizing platinum-cured systems that yield superior tensile strength and absolute material purity.
Pet Care Products
The booming pet industry requires robust, non-toxic materials. Our sample range includes chew-resistant toys, collapsible travel bowls, and grooming brushes. We utilize customized durometers (hardness) to match the specific bite force and interaction style of different animals, ensuring longevity and safety for beloved pets.
Uncompromising Quality & Consistency
A prototype is only valuable if it accurately represents the final manufactured product. One of the most common pitfalls in outsourced manufacturing is the "bait and switch"—where high-quality samples are provided, but mass production yields inferior results. We fundamentally reject this practice.
At Kingod, our core engineering philosophy mandates that samples use the same material and process as mass production to ensure consistency. When you approve a custom sample, you are approving the exact chemical formulation, the specific platinum or peroxide curing agent, the precise Pantone color masterbatch, and the identical molding parameters (temperature, pressure, cure time) that will be deployed in full-scale manufacturing.
Our state-of-the-art laboratory facilities conduct rigorous First Article Inspection (FAI) on all custom prototypes. We utilize advanced metrology equipment, including optical comparators and 3D coordinate measuring machines (CMM), to verify that the physical sample matches your 2D drawings and 3D CAD models down to microscopic tolerances.

Frequently Asked Questions About Silicone Sampling
Q: Are standard silicone samples genuinely free of charge?
Yes, absolutely. To assist our prospective B2B partners in evaluating our material quality and manufacturing capabilities, we provide standard stock samples and material swatches completely free of charge. The only cost incurred by the customer is the international express shipping fee (freight collect or pre-paid via your courier account).
Q: How does the refund policy for custom sampling fees work?
We view custom prototyping as a collaborative investment. While we charge an initial sampling fee to cover the costs of rapid CNC tooling, custom material mixing, and machine setup time, this fee is fully deductible from your subsequent mass production order, provided the order meets our minimum order quantity (MOQ) threshold. This ensures your R&D budget is effectively utilized toward your final product.
Q: Can I request samples with specific regulatory certifications like FDA or LFGB?
Certainly. Depending on your industry—be it baby products, food-contact kitchenware, or medical devices—we will utilize raw silicone materials that already hold the necessary certifications (FDA, LFGB, RoHS, REACH, USP Class VI). We can provide the corresponding Material Safety Data Sheets (MSDS) and certification documents alongside your physical samples for your compliance records.
Q: What is the difference between a prototype mold and a mass production mold?
Prototype molds are typically single-cavity tools machined from softer metals like high-grade aluminum or pre-hardened steel (P20). They are designed for speed and cost-efficiency to produce a limited run of samples (usually 10-50 pieces) for testing. Mass production molds are multi-cavity, machined from hardened tool steel (like S136), designed to withstand hundreds of thousands of injection or compression cycles with zero degradation, ensuring long-term unit cost reduction.
Q: How long does it take to manufacture a custom silicone sample?
While standard stock samples are dispatched within 3 to 7 days, custom engineered prototypes require tooling fabrication. Generally, upon approval of the 3D CAD design and confirmation of material specifications, custom compression molded samples take approximately 7 to 12 days to produce. Complex Liquid Silicone Rubber (LSR) injection molded prototypes may require 12 to 18 days due to the intricate nature of cold-runner tooling systems.
Q: Can you match my exact corporate brand colors?
Yes, silicone is highly receptive to pigmentation. We utilize advanced colorimetry and high-quality masterbatches to match any Pantone Matching System (PMS) or RAL color code you specify. We can also provide samples with special visual effects, including translucent, highly transparent (optical grade), glow-in-the-dark, or custom metallic flake integrations.
