Tools & Equipment Manufacturing

Low-volume production runs often present the challenge of balancing cost-efficiency with the need for high-quality components. For example, when working with clients in industries like medical devices or automotive, we face the task of producing specialized parts in smaller quantities without sacrificing performance or precision. KingStar Mold uses several methods to achieve cost-effective production while ensuring high quality:

1. Rapid Tooling (Soft Molds):

   • In low-volume production, we use rapid tooling methods, such as soft molds, which are less expensive and quicker to produce than traditional steel molds. This helps reduce initial tooling costs without compromising the ability to produce high-quality parts.

2. Design for Manufacturability (DFM) Optimization:

   • We carefully assess each design and recommend adjustments to make parts easier and cheaper to manufacture. This can include reducing part complexity, optimizing wall thickness, incorporating draft angles for better mold release, and selecting materials that are easier to process.

   • For example, we might suggest simplifying part geometries or incorporating standard features that can be easily molded, reducing both production time and cost.

3. Material Selection for Cost and Performance Balance:

   • Choosing the right material is crucial in low-volume production. We leverage a variety of materials based on their cost-effectiveness and performance requirements. For example, we may opt for thermoplastics or commodity metals instead of high-cost superalloys when the application permits, ensuring cost savings while maintaining performance.

4. Injection Molding with Multi-Cavity Molds:

   • We use multi-cavity injection molds, which allow multiple parts to be produced in a single cycle, increasing throughput and reducing the per-unit cost. This method is particularly useful for parts that are relatively simple but require high precision and uniformity.

5. 3D Printing for Prototyping and Low-Volume Runs:

   • For certain applications, we use 3D printing as a rapid prototyping and production method, especially for parts that are geometrically complex or require design iterations. 3D printing helps in reducing setup costs and lead times, enabling faster turnarounds for low-volume runs.

6. Lean Manufacturing and Waste Minimization:

   • Our production processes are optimized using lean manufacturing principles, which focus on reducing waste, optimizing workflows, and improving efficiency. We also utilize regrind materials and minimize scrap during production to further reduce costs.

7. Flexible Production Scheduling:

   • By leveraging flexible production scheduling, we can accommodate varying production volumes without incurring significant overhead costs. This flexibility allows us to adjust quickly to client needs, whether for small, high-quality runs or larger orders.

Quality Control:
Despite the cost-saving methods, we maintain stringent quality checks throughout the process:

• In-Process Monitoring: During production, we continuously monitor key parameters like temperature, pressure, and material flow to ensure consistency and avoid defects.

• Post-Production Testing: Every batch undergoes rigorous testing, including dimensional inspection using CMM (Coordinate Measuring Machines) and functional testing to ensure parts meet the specified requirements.

By applying these methods, KingStar Mold successfully delivers high-quality, cost-efficient parts for low-volume production runs. This ensures that our clients receive reliable components that meet their performance standards, while also keeping production costs within budget.

KingStar Mold frequently handles complex industrial parts requiring tight tolerances. For example, we worked with a client in the aerospace industry to produce aluminum brackets for aircraft assemblies. These parts required both lightweight properties and precise dimensional accuracy to fit seamlessly within the overall assembly.

Solution:

• Machining Process: We utilized high-precision CNC machining and EDM (Electrical Discharge Machining) to create the complex geometries and intricate details necessary for the parts.

• CNC Machines: Our multi-axis CNC machines allowed us to meet tight tolerances and produce parts with exceptional accuracy, even for challenging geometries.

• EDM Process: For parts with delicate features such as small holes or internal grooves, EDM was used to achieve fine details that conventional machining could not produce.

Quality Control:

• CMM (Coordinate Measuring Machines): Regular inspections using CMM ensured the parts consistently met the required tolerances (within ±0.002″).

• Final Inspection: Before delivery, all parts underwent stringent quality checks to confirm they fit correctly within the assembly, minimizing the risk of operational failures.

By using advanced machining techniques and comprehensive quality control, we successfully delivered high-precision parts that met all dimensional requirements, ensuring reliable performance within the client’s aerospace assembly.

Material selection plays a critical role in determining the performance, durability, and cost-efficiency of manufactured tools and equipment. At KingStar Mold, we work with a wide range of materials—both metals and plastics—to meet the functional and environmental demands of various industrial applications.

Below are the most commonly used materials and why they’re preferred:

1. Steel and Stainless Steel

• Strength and Durability: Steel is widely used for structural parts, inserts, and heavy-load components due to its excellent strength and wear resistance.

• Corrosion Resistance: Stainless steel, in particular, is favored in harsh environments such as oil and gas or marine applications where corrosion resistance is essential.

• Precision Machinability: Both materials are suitable for CNC machining, allowing for high-precision industrial and tooling parts with tight tolerances.

• Use Cases: Mold inserts, pump parts, brackets, and machine bases.

2. Aluminum

• Lightweight and Strong: Aluminum offers a favorable strength-to-weight ratio, which is ideal for portable tools and equipment.

• Excellent Machinability: Its soft, easy-to-machine nature makes it ideal for both prototyping and production machining.

• Corrosion Resistance: Naturally forms an oxide layer, and can be further enhanced with anodizing.

• Use Cases: Equipment housings, handheld tools, cooling components, and structural frames.

3. Engineering Thermoplastics (PEEK, PA, PC, etc.)

• High Mechanical Performance: Thermoplastics like PEEK, Nylon (PA), and Polycarbonate (PC) offer strength, temperature resistance, and chemical stability.

• Metal Replacement: High-performance plastics can serve as metal alternatives in non-load-bearing or chemically exposed environments.

• Use Cases: Insulating housings, brackets, handles, and seals.

4. Commodity Plastics (ABS, HIPS, PP, etc.)

• Cost-Effective: Materials like ABS, HIPS, and Polypropylene (PP) are affordable and easy to process in high volumes.

• Versatile Applications: While not as strong as engineering plastics, they’re perfect for non-structural parts or components that don’t face extreme conditions.

• Use Cases: Enclosures, control knobs, covers, and light-duty components.

5. Elastomers and Rubbers (TPU, Silicone, etc.)

• Flexibility and Impact Resistance: Thermoplastic polyurethane (TPU) and silicone rubber are used where elasticity, cushioning, or sealing is required.

• Chemical and Fuel Resistance: Suitable for environments with fluid exposure, including automotive and industrial applications.

• Use Cases: Gaskets, seals, shock absorbers, and protective pads.

6. Superalloys (e.g., Inconel)

• High-Temperature Strength: Materials like Inconel are used in applications exposed to extreme heat or pressure.

• Specialized Use: Often chosen for highly demanding environments where conventional metals would degrade.

• Use Cases: High-performance inserts, aerospace-grade tool components, and oilfield parts.
