Who We Are: Your One-Stop Custom Manufacturing Partner
At Sunmy Hardware, we’re more than just a “manufacturer”—we’re a ** 工贸一体 (industry-trade integrated)** 外贸公司 (foreign trade company) dedicated to custom production. Our strength lies in our ability to take a client’s concept, drawing, or sample and transform it into a finished product that meets their exact specifications. What sets us apart? A powerful, end-to-end production system that covers every critical step of the manufacturing process:
- Casting: For complex, near-net-shape metal components that require strength and precision.
- Lathe Machining: For cylindrical parts with tight tolerances, ensuring consistency across every unit.
- CNC Machining: For intricate, custom-designed parts that demand accuracy and repeatability.
- Stamping: For high-volume, cost-effective metal parts ideal for automotive, electronics, and industrial applications.
- Injection Molding: For plastic components in various shapes and sizes, perfect for consumer goods and medical devices.
Backed by a team of engineering and manufacturing experts, we don’t just “produce”—we collaborate. Whether you’re a startup with a prototype or a Fortune 500 company needing a scalable production partner, we take the time to understand your goals, address potential challenges, and deliver solutions that align with your timeline and budget.
Custom Production Success Stories: Clients We’ve Empowered
Every client’s needs are unique, and so are our success stories. Below are a few examples of how we’ve turned custom requirements into successful outcomes—helping businesses across industries bring their products to life.
1. Automotive Component: From Sketch to Mass Production
A leading automotive parts supplier approached us with a challenge: they needed a custom aluminum casting part for a new electric vehicle (EV) model. The part required complex geometry to fit tight engine bay spaces, plus high heat resistance to withstand EV operating conditions.
Our Solution:
- First, our engineering team reviewed their 3D drawings and conducted feasibility tests to optimize the casting design (reducing material waste and improving structural integrity).
- We used our precision casting equipment to create a prototype, which underwent rigorous testing (including heat and pressure simulations) to meet the client’s standards.
- Once approved, we scaled up production using our automated lathe and CNC machining lines—delivering 10,000 units per month with a 99.8% defect-free rate.
The Result: The client launched their EV model on schedule, and our component became a key part of their supply chain. They’ve since expanded their partnership with us to develop 3 more custom parts for future models.
2. Industrial Equipment: Custom Machined Parts for Heavy-Duty Use
A manufacturer of industrial pumps needed a replacement for a critical stainless steel part that was breaking down prematurely in harsh, chemical-rich environments. They provided a sample and requested a more durable, corrosion-resistant version—with a 4-week turnaround to avoid production downtime.
Our Solution:
- We analyzed the original part’s material and design, recommending a switch to 316L stainless steel (known for superior corrosion resistance) and adjusting the machining tolerances to improve fit.
- Our machining team used 5-axis CNC equipment to produce the first batch of 50 parts in just 2 weeks—half the requested timeline.
- We conducted third-party testing to verify corrosion resistance, ensuring the parts would outlast the original by 3x.
The Result: The client’s pumps resumed operation without delay, and the new parts reduced their maintenance costs by 40%. They now rely on us for all their custom machined part needs.
3. Consumer Electronics: Injection-Molded Plastic Casings for a New Gadget
A tech startup came to us with a prototype for a portable smart sensor—needing a sleek, lightweight plastic casing that could protect internal components while fitting in a user’s pocket. They had a tight budget and needed to test market demand before scaling up.
Our Solution:
- We worked with their design team to refine the casing’s ergonomics (adding a non-slip grip and improving airflow) and selected a durable, recycled ABS plastic to meet cost goals.
- Using our small-batch injection molding capabilities, we produced 500 casings in 1 week—allowing the startup to launch a beta test quickly.
- After positive market feedback, we scaled production to 10,000 units per month, adding custom color options to match their brand.
The Result: The startup’s sensor became a top-seller in its category, and our flexible production approach helped them avoid overinvesting in inventory upfront.
