Shanrun Toys × Speks:TPR Stress Relief Toys: Pain Points and Successful Amazon Sales Cases

In 2024, the well-known stress relief toy brand Speks faced industry-wide common pain points related to TPR material toys in terms of safety, performance, craftsmanship, and quality control. As a result, the company reached a deep DOM cooperation with Shanrun Toys to jointly solve the entire TPR stress relief toy chain problems and create a best-selling product that meets European market standards.

Excessive Hazardous Substance Content: Ordinary TPR formulations tend to retain formaldehyde, TVOC, phthalates, xylene, etc., which do not meet standards such as GB 6675, EU EN71, US CPSC, ASTM F963. Products may be removed from the Amazon platform due to compliance issues.

Strong Odor: Poor quality plasticizers and fillers cause heavy off-gassing at the factory, resulting in poor user experience and a high number of negative reviews, mainly focusing on "unpleasant smell, not safe for children to play with".

Environmental Protection and Contact Safety: Poor material compatibility leads to oil leakage and color fading, which may cause skin allergies over time and do not meet European toy safety requirements.

(2) Physical Performance Pain Points (Failure of Core Stress Relief Function)

Poor Elasticity: Ordinary TPR is prone to permanent deformation, creases, and collapse, and cannot quickly recover after compression, significantly reducing the stress relief experience.

Insufficient Durability: Repeated kneading leads to cracking, delamination, layering, and shedding of the product, resulting in short product lifespan and low user repurchase willingness.

Poor Hand Feel: Inadequate hardness and sticky/dry surface, lacking the Q-like softness for stress relief, unable to meet the core need of "pinching and releasing stress" for users.

(3) Production Process Pain Points (Challenges in Mass Production and Quality Control)

Frequent Injection Defects: Soft TPR has strong fluidity, prone to fly edges, sticking to molds, white spots, bubbles, shrinkage, and flow patterns, resulting in low yield and high production costs.

Inconsistent Shape and Size: Uneven cooling, high internal stress, product deformation and size deviation the next day, unable to meet standardized mass production requirements.

Difficult Demolding and Molding: High friction coefficient of soft TPR, insufficient demolding slope leads to cracking, complex shapes with incomplete filling and missing glue.

(4) Market Adaptation Pain Points (Weak Competitiveness on the Amazon Platform)

Severe Homogeneity: Product designs and functions are monotonous, lacking differentiated selling points, making it difficult to stand out among the vast number of competing products on Amazon.

Unstable Quality Control: Large batch variations, high Amazon user negative review rates, affecting store ratings and traffic.

Cost and Delivery Imbalance: High costs for small batch customization and long delivery times, unable to meet the rapid replenishment requirements of Amazon.

Self-developed Eco-friendly TPR Formula: Shanrun collaborates with material suppliers to develop TPR formulas without phthalates, formaldehyde, and high VOC content, replacing inferior plasticizers with three times hydrogenated paraffin oil, effectively eliminating harmful substance residues from the source.

Comprehensive Compliance Testing: Each batch of products undergoes authoritative tests such as SGS, CPSC, EN71, and ASTM F963 to ensure that indicators such as formaldehyde, TVOC, phthalates, and xylene are far below the limits of national and European standards.

Odor and Contact Safety Optimization: Add low-odor stabilizers to the formula, resulting in no strong odor at the time of product release. Improve material compatibility, solve problems such as oil leakage, color fading, and allergic reactions, and meet the safety requirements for direct skin contact.

(II) Physical properties: Material modification + structural design, creating an ultimate stress-relieving experience

Customized high-resilience TPR: Optimizing material hardness (30A–50A) and cross-linking structure, achieving 100% rapid rebound, and no permanent deformation or creases after repeated kneading up to 100,000 times.

Enhanced durability improvement: Through molecular chain strengthening technology, enhancing the material's resistance to tearing and aging, solving cracking, delamination, and chipping problems, and increasing product lifespan by more than 3 times.

Precise control of Q-bounce feel: Adjusting the material's softness and surface smoothness to create a soft, Q-bouncy, and non-slip touch, perfectly matching users' stress-relieving kneading needs.

(III) Production process: Mold optimization + precise parameter adjustment, achieving efficient and stable mass production

Mold design upgrade:

The demolding slope of soft TPR products is 1.5°–3° on one side, and the deep cavity products have a larger slope. Combined with a punch + top plate for top-out, it solves mold sticking and cracking problems.

Optimizing the uniform layout of the cooling water channels and adding exhaust grooves to solve bubble, shrinkage, and deformation problems.

Complex shapes use multi-section gates + vacuum exhaust to ensure complete filling and no missing glue.

Precision adjustment of injection parameters:

Using a low-temperature, low-pressure, and slow injection process (material temperature 160–180℃, injection pressure 50–80MPa, medium-low speed injection), avoiding flash, flow patterns, and melt rupture.

The holding pressure adopts a low-pressure, long-time, and multi-stage decreasing strategy, with uniform secondary flow and reduced internal stress.

The cooling time is 15–30 seconds, ensuring the product is fully cured before being ejected, preventing deformation the next day.

Full-process quality control: From raw material storage, injection, trimming, packaging to shipment, setting 12 quality inspection checkpoints, with a pass rate of over 98%.

(IV) Market adaptation: Differentiated customization + flexible production, empowering the creation of Amazon best-selling products

ODM differentiated design: Combining Speks brand positioning and Amazon user preferences, designing series such as cute pet simulations, fun geometries, and stress-relieving boxes, adding night light, gradient, and fragrance as differentiated selling points, to create exclusive bestsellers.

Flexible production delivery: Shunrun has 10 standardized production lines, supporting small-batch rapid prototyping and large-batch stable delivery, reducing delivery time by 30% and meeting Amazon's rapid replenishment needs.

Amazon operation empowerment: Shunrun provides product compliance reports, high-definition main image videos, A+ page materials, assisting Speks in optimizing the listing, improving search rankings and conversion rates.

Four, cooperation achievements (Amazon best-selling products and win-win for customers)

Double harvest of compliance and reputation: The cooperative products 100% passed authoritative inspections in Europe and the United States, successfully listed on Amazon US and European sites, without compliance removal risks; user reviews increased from 3.2 stars to 4.8 stars, "safe, no odor, good rebound, and good feel" becoming frequent praise words.

Amazon performance explosive growth:
