Support
Talk to our experts with 10+ years of experience in injection molding for help with mold design, material selection, and finishes—making the whole process smoother.
We value quality from design to production. Cross-team
reviews and strict controls help achieve a 90% first-pass yield for all plastic molded parts.
Mold and Pre-produdction
Inspection
Proper mold design and pre-production checks are
key to injection molding quality. Engineers consider part geometry,
material flow, and cooling systems to guarantee smooth production. Trial
molds are tested to confirm all functions work correctly, providing
stable and consistent results.
In Process Quality Control
Continuous checks during production keep custom
molded parts consistent. Injection machine parameters such as speed,
pressure, and temperature are monitored within set limits. Regular
inspections of part dimensions and appearance help detect and fix issues
quickly.
Final Inspection
Completed parts undergo thorough final inspection
to meet design and quality standards. Teams check dimensions,
appearance, and physical properties. Precision instruments like
coordinate measuring machines (CMM) and colorimeters verify that all
components meet strict standards.
Injection molding is huge in making a
ton of products—anything from car parts to medical devices. It’s
super efficient because it can produce lots of identical plastic parts with
tight tolerances, all at a low cost per part. That’s why so many
industries rely on it for mass production. Whether it’s a simple or
complex design, it keeps quality high and production fast.

Injection Mold Tooling FAQs
How long does it take to receive a part once an order is placed?
The lead time for receiving a CNC machined part from XCD can vary depending on several factors including the complexity of the part's design, the type of material selected, and our current production schedule. CNC machining is known for its speed, particularly for less complex parts, allowing for quick turnaround times. In fact, parts can be delivered in as fast as just one day after the machining setup is complete! However, for the most accurate time estimate tailored to your specific project, we recommend contacting us directly for a detailed quote. This way, we can provide you with a precise timeframe based on your unique requirements.
How much does your CNC machining service cost?
At XCD, every product goes through strict verification—from trial production and inspection testing to customer confirmation—before shipment. Our quality assurance process ensures that all parts meet the agreed specifications before delivery, minimizing the risk of nonconformities. We take pride in our precision and reliability, and every shipment is the result of a joint confirmation between our engineers and customers.
Is there a minimum order quantity (MOQ) for CNC machining at XCD?
At XCD, we understand the diverse needs of our customers, ranging from single prototypes to large-scale production runs. Consequently, we do not enforce a strict minimum order quantity (MOQ). Whether you require just one machined part or thousands, we are equipped and ready to provide tailored solutions that meet your specific requirements. Our flexible approach ensures that all clients, regardless of order size, receive the highest level of service and quality.
What are the advantages and disadvantages of CNC machining?
Advantages of CNC Machining
Precision and Repeatability: CNC machining ensures high precision and consistent replication of parts, crucial for complex designs with tight tolerances.
Reduced Human Error: The automated nature of CNC machining minimizes human error, enhancing the overall quality of production.
Efficiency and Speed: Automation allows for faster production cycles, enabling quicker turnaround times than manual processes.
Material Flexibility: CNC machines can work with a diverse range of materials, including metals, plastics, and composites, offering versatility across various applications.
Software Integration: Advanced CNC software supports quick design changes and updates, facilitating rapid prototyping and easy customization.
Cost-Effective for Large Runs: While setup costs are higher, per-unit costs decrease significantly with larger production volumes, making it cost-effective for mass production.
Disadvantages of CNC Machining
High Initial Costs: CNC machinery and its maintenance represent significant investments, making initial setup expensive, especially for small-scale operations.
Skill Requirements: Operating CNC machines requires highly skilled personnel, which can increase training costs and limit accessibility.
Less Cost-Effective for Small Runs: Due to setup and programming time, CNC machining may not be economical for producing small quantities of parts.
Material Waste: CNC machining often involves subtractive processes, leading to more material waste compared to additive manufacturing.
Limited to Material Hardness: Extremely hard materials can wear out CNC tools quickly, potentially increasing operational costs and downtime.
