Are you looking for custom parts that fit your specific engineering needs? Non-standard precision parts give solutions where industry‐standard parts may not fit．
In this blogpost we will highlight all important information about these custom parts. We will also see how they are manufactured and where they get used.
What are Non-Standard Precision Parts?
Manufacturers produce non-standard precision parts to meet needs that standard parts cannot meet. These personalized parts do not adhere to industry standards. Mainly they are made according to customer drawings which makes sure that each and every component is exactly suited to its intended use.
Characteristics
Non-standard precision parts obtain highly fine tolerances, in certain cases reaching ±0.001 mm. Manufacturing is often done in small batches. These parts mostly require intricate shapes or cutting‐edge materials. Each project has its own finish, design and quality standards so these parts provide greater adaptability. This personalization makes production more costly and difficult.
Non-Standard vs. Standard Precision Parts
In precision manufacturing it is necessary to understand the difference between non-standard & standard parts. This knowledge will help you make better decisions purchasing, design and production. The below given table outlines some of the key differences.
| Criteria | Non-Standard Precision Parts | Standard Precision Parts |
|---|---|---|
| Design parameters | Personalized‐designs that depend on particular functional demands; no predetermined standards. | Complies with industry protocols (DIN, ISO, ANSI); predetermined tolerances & dimensions. |
| Lead Time & Availability | Prolonged lead times; needs prototyping, design & custom production. | Short buying times; easily available since mass‐produced. |
| Manufacturing Complexity | Intricate procedures that need accurate engineering & special tooling. | Basic, large‐scale production procedures; lower production intricacy. |
| Application Specificity | Important for advanced sectors (medical devices, aerospace & automotive). | Works well for common‐purpose industrial uses. |
| Cost Implications | Greater manufacturing expense justified by real‐life needs & efficiency. | Less unit cost because of economies of scale; budget‐friendly for common use. |
Manufacturing Process of Non-Standard Precision Parts
EDM (Electrical Discharge Machining)
EDM manufactures fine internal features and sharp corners in non-standard parts that conventional machining cannot create. This procedure typically obtains tolerances ranging from ±0.005 mm to ±0.0025 mm. Under certain conditions EDM can achieve even tighter tolerances; this depends on material and intricacy of the part.

CNC Machining
In CNC machining, computer‐controlled cutting tools form custom precision parts. This approach obtains tolerances of up to ±0.0025 mm for non-standard parts. Advanced CNC systems – i.e. RICHCONN’s 5‐axis machining centers – can create intricate geometries with multiple curved surfaces. These systems also produce precision molds for the production of custom components.

Additive Manufacturing
Additive manufacturing – also called 3D printing – creates non-standard parts by adding material layer by layer. This method is suitable for small‐scale manufacturing and fast prototyping of non-standard parts. Accuracy depends on the technology that is being utilized but tolerances of ±0.1 mm are common. Some modern systems can obtain even stricter tolerances.
Quality Control
Engineers use stringent standards as well as modern inspection equipment to guarantee quality control for non-standard precision parts. Coordinate Measuring Machines (CMM) verify dimensions with micron‐level accuracy which confirms that each feature is according to the design.
Optical process or profilometers evaluate surface finish where roughness values as low as Ra 0.1 μm are specified for difficult use cases. These detailed checks ensure that each component complies with the rigorous specifications and performs well in its intended use.
At RICHCONN, our ISO 9001:2015-certified quality system utilizes high-tech optical measurement systems, CMMs and materials testing to confirm every surface detail and dimension before shipment.

Uses of Non-Standard Precision Parts
Industries depend greatly on non-standard precision parts when standard parts cannot meet particular performance or design needs. These components are used in multiple industries:
Medical Field
In medical field, precision‐machined components are critical. They are used in ear implants, artificial joints, small screws and pacemaker parts. These components must withstand cleaning chemicals and meet strict biocompatibility standards.
Aerospace
Non-standard precision parts play a very important part in aerospace for both spacecraft & aircraft. They are useful in producing landing gear parts, personalized turbine blades and intricate engine components built to withstand high loads and temperatures.
Industrial Machinery
Special tooling, robotic arms, fixtures as well as intricate assembly systems in industrial units rely on non-standard parts. These parts increase reliability & efficiency which assist engineers to rapidly adapt to changing manufacturing needs and make their products unique.
Automotive
Non-standard precision manufacturing is usually essential for custom suspension systems, prototype components for testing & special engine parts. These components permit manufacturers to assess new designs and also evaluate advancements before large‐scale manufacturing.
Real-World Examples
Example‐1: Building a special bracket for medical imaging equipment
A medical equipment engineer needed a lightweight, corrosion‐resistant bracket for a critical imaging device. Our team picked titanium & used modern CNC methods to achieve strict tolerances of ±0.02 mm. The custom‐made component reduced the weight of equipment & preserved structural durability at the same time.
Example‐2: Construction of a custom gear for a high performance engine
An automotive customer needed a gear with special tooth geometry for his racing engine. We employed CNC machining to obtain ±0.01mm accuracy and minimized the weight of the gear by 15%. This improved gear enhanced torque delivery and tolerated high RPMs. This increased the efficiency & reliability of customer’s engine.
Limitations & Considerations
Design Complexity
Experienced labor and modern manufacturing procedures are necessary to handle complex geometries with walls less than 0.8 millimeter thick or deep cavities. Designs with such intricacies usually require EDM or multi‐axis machining which increases both manufacturing time & technical specifications.
Cost Implications
Small manufacturing batches, custom materials and strict tolerances usually make custom components more expensive as compared to standard parts. Extra finishing procedures – like obtaining single‐digit Ra surface finishes – further increase expense. RICHCONN solves this problem by thoughtfully picking materials & by optimizing production methods to deliver quality while managing costs.
Lead Times
Custom parts take more time to manufacture as compared to standard components. The special nature of non-standard parts required additional material sourcing, design collaboration and thorough quality control. Guaranteeing uniform quality during manufacturing also adds to the lead time.
RICHCONN minimizes these slowdowns through detail‐oriented project management and just‐in‐time production which reduces lead times by up to 30% in contrast to certified standards.
