At Hipins, trust is not built overnight—it’s forged through consistent quality, reliable service, and shared success. In this latest case study, we proudly present a project that exemplifies the power of long-term collaboration: a repeat customer placed a large-volume order of two custom pins without requesting any sampling. This level of trust didn’t happen by chance—it’s the result of years of seamless cooperation, outstanding results, and unwavering commitment to excellence.
Project Overview: Two Variants, One Seamless Process
The order included two distinct pin designs—Model A and Model B—both sharing the same structure but differing in color palette and finish. Unique effects were used in both versions, including:
- Pearlescent powder gradient (non-mixed)
- Transparent sandblast fill
Thanks to our streamlined internal processes and experienced team, the order was completed swiftly, and the final product exceeded expectations—both in visual appeal and production speed.
Let’s take you behind the scenes of how we made it happen, from mold making to the final boxed pins.
1. Mold Creation: The Blueprint of Precision
As no sampling phase was required, our production process began directly with mold making. Since we had previously worked with this client, we already had a deep understanding of their brand standards and design expectations. However, the new design still required technical accuracy, especially because two separate color schemes would rely on the same base mold.
Innovative approach:
To avoid minor misalignment or inconsistencies across the A and B versions, our engineers implemented a double-verification process during CNC mold engraving. Using 3D software simulation, we ensured that each groove and level of relief would accommodate both color sets without spillage or imbalance.
We then hardened and polished the mold with our precision heat treatment techniques, ensuring long-lasting durability for large-volume production. The mold was ready in under 48 hours.
2. Coloring: Precision Gradient with Pearlescent Powder
The coloring stage was where the pins truly began to shine—literally. Both pins used pearlescent powder, but in gradient form and without mixing. This technique is notoriously difficult because:
- The powder tends to settle quickly.
- Achieving a smooth gradient requires expert layering and precise timing.
Our innovation:
We applied a “step-feed” color layering process developed in-house, allowing us to control the density and dispersion of the pearlescent particles across each section of the pin. By using low-speed automated dispensers and manual gradient adjustments, we created a smooth transition that looks like soft waves under light.
Each pin was baked in a humidity-controlled oven to lock in the gradient effect and prevent pigment migration. Model A used cooler tones—sky blue to lavender—while Model B adopted warmer transitions of amber to rose pink.
3. Special Effects: Transparent Sandblast Application
Next came the application of transparent sandblasting, a technique that creates a frosted texture within transparent enamel areas. This effect adds both depth and a unique tactile quality to the pins.
We created micro-etches within specific zones of the mold, then applied high-clear epoxy infused with fine glass powder. Once cured, the result was a semi-transparent, matte-like appearance—eye-catching but subtle.
This feature was key to distinguishing the high-end look of these pins and aligns perfectly with the client’s premium brand image.
4. Finishing Touches: Printing and Polishing
Though the pins didn’t require elaborate printed details, we did apply silkscreen outlines for branding clarity and enhanced contrast. Our silkscreen frames are custom-fitted to every batch, ensuring sharp and consistent application.
Polishing was done in two stages:
- Tumbling polish to smooth out edges and remove excess debris.
- Manual high-gloss polish on the raised metal areas to add brilliance and visual contrast.
Each pin was then carefully quality checked under strong white light to catch any flaws in the enamel flow, metal finish, or printing alignment.
Client Communication: Trust-Driven Efficiency
Because of our longstanding relationship with this client, the communication process was efficient and minimal. Still, we maintained:
- Full project tracking with visual updates.
- Batch-by-batch photo confirmation.
- Advanced notice of shipping and packaging specs.
As a gesture of appreciation, we offered free expedited shipping and added customized packaging at no extra cost.
What Sets Hipins Apart in Repeat Orders
This project is a great example of how Hipins supports long-term clients through:
- Confidence in quality: Our clients trust us to deliver mass orders without sampling.
- Speed without compromise: We completed this high-volume, multi-effect project in record time.
- Material mastery: From pearlescent powder to transparent sandblast, we expertly handled complex finishes.
- Consistent communication: Even with minimal back-and-forth, we ensured every detail was confirmed.
Q1: Can you produce gradient colors without mixing them together?
Yes! Our team uses a special step-feed technique to apply pearlescent gradients in layers, keeping them distinct and smooth.
Q2: What is transparent sandblasting?
It’s a technique where frosted textures are created beneath clear enamel to give a soft matte effect. It adds sophistication to the pin’s look.
Q3: Do I need to sample before a mass order?
While sampling is recommended for first-time projects, returning clients with established specs may choose to go straight to mass production.
Q4: Can I combine different special effects in one pin?
Absolutely. We specialize in multi-technique pins that combine gradients, glitter, transparent fills, and screen printing.
Q5: How fast can you finish large-volume orders?
With our factory setup and optimized workflows, we can deliver most complex bulk orders within 7–12 days, depending on specs.
