Custom Parts We Have Manufactured
Explore nine custom part examples. The requirements and proposed solutions below are design guidance for similar projects; your specification and validation plan are confirmed during review.
Custom Molded Mask
- Requirement
- A flexible profile that follows a defined contour and aligns with adjoining components.
- Proposed solution
- Develop the molded contour, edge thickness and openings around your drawing; check fit and flexibility with samples.
Angle Components
- Requirement
- An angled part with controlled leg lengths, wall thickness and connection points.
- Proposed solution
- Review the angle, internal radii and mating dimensions, then sample the geometry for assembly checks.
Coupling Element
- Requirement
- A flexible element that fits between mating components under specified movement and load.
- Proposed solution
- Define the interface geometry and compound hardness; evaluate sample fit and behavior under your operating conditions.
Silicone Keypad
- Requirement
- Keys that align with an enclosure and deliver the required feel and return.
- Proposed solution
- Review key spacing, travel, web thickness, color and marking needs; validate sample actuation in the intended assembly.
Custom Connectors
- Requirement
- A non-standard connection profile with a secure fit at each interface.
- Proposed solution
- Match the openings, wall sections and retention features to the mating parts; check assembly and any required sealing performance.
Protective Boot
- Requirement
- A flexible cover that accommodates movement around a joint or connection.
- Proposed solution
- Review the opening sizes, folds and travel envelope; test sample clearance and retention through the required movement.
Silicone Brushes
- Requirement
- A custom brush shape with the required reach, flexibility and contact area.
- Proposed solution
- Review bristle length, spacing, base shape and hardness; assess sample flexibility and cleaning access for the intended use.
Molded Grips
- Requirement
- A grip that fits its handle and provides the intended texture and feel.
- Proposed solution
- Tailor the internal profile, wall thickness and surface texture; check sample installation, comfort and resistance to slipping.
Sealing Elements
- Requirement
- A sealing profile that fits the available space and intended compression.
- Proposed solution
- Review the cross-section, mating surfaces, medium and temperature; validate dimensions and sealing performance under agreed test conditions.
Drawing Submission Checklist
Include these details with your inquiry to help us review the design and prepare a quote. If a detail is undecided, tell us what the part needs to achieve.
Drawing or reference sample
Send a dimensioned PDF and, if available, a STEP or IGES model. Include units, part number and revision. If you only have a sample, share photos and key dimensions first so we can confirm the next step.
Dimensions & tolerances
Mark critical dimensions, mating surfaces, wall thickness and acceptable tolerances. Include an assembly drawing or mating-part details where fit is important.
Material & working conditions
Specify the material and hardness scale if known, or describe the application, temperature range, contact medium, movement and load.
Appearance & special requirements
Include the Pantone reference, texture, markings and acceptable flash or parting-line locations. Identify any application-specific standards or performance requirements.
Quantity & timing
State the sample quantity, initial order and expected repeat demand, plus your required sample date, production date and delivery destination.
Acceptance criteria
List dimensional, visual and functional checks, test conditions, acceptance limits and required reports. Identify who will approve the samples and release production.
Discuss Your DrawingStart with an inquiry; we will confirm how to share your files or send a physical sample.
MATERIAL SELECTION
Material Options
Choose around the job your custom part must do. Use these starting points to discuss the compound, geometry and sample checks with us.
Natural Rubber (NR)
For parts that flex and recoverConsider NR for a custom mount or buffer that needs elastic recovery and tear strength. Share the load and movement range so we can review the shape and hardness; flag any oil or outdoor exposure.
Nitrile (NBR / BUNA-N)
For a seal designed around oil contactNBR is a starting point for custom gaskets and seals in lubricated assemblies. Identify the oil and temperature, then define the mating dimensions and compression needed for sample testing.
Fluorocarbon (FKM)
For demanding heat and fluid exposureDiscuss FKM when a custom seal must combine heat resistance with oil or fuel contact. List every fluid, concentration and temperature extreme so the grade can be reviewed before tooling.
Silicone (VMQ)
For flexible shapes across heat and coldConsider silicone for a custom keypad, plug or flexible cover where temperature flexibility matters. Define the feel, wall thickness and color; identify thin edges and rubbing surfaces for sample evaluation.
Neoprene (CR)
For a protective part with mixed demandsCR offers a useful balance for custom boots and covers facing weathering, handling and occasional oil contact. Share the movement envelope and exposure conditions to guide profile and hardness choices.
EPDM
For outdoor or water-exposed profilesConsider EPDM for a custom enclosure gasket or water-contact seal where weathering resistance is a priority. Define the sealing gap and compression, and identify any petroleum oil or fuel contact before selection.
Confirm the details that matter
- Temperature
- Compound-specific; confirm your service conditions.
- Tensile strength
- Depends on the compound and test method.
- Abrasion resistance
- Confirm by testing. Silicone is generally poor; verify the compound performance.
These are starting points for design review. Confirm the selected compound against your operating conditions and sample acceptance criteria. Temperature suitability depends on exposure duration, medium and load; dry-air ratings do not establish steam-service limits.
HOW IT WORKS
From Drawing to Delivery
Agree on the tooling, samples and acceptance criteria before production. Timing is confirmed for your design, tooling needs and order quantity.
Drawing & feasibility review
Share the submission checklist below. Confirm the drawing revision, material, critical dimensions, tolerances, quantity and acceptance criteria before proceeding.
Tooling approval
For parts requiring a mold, agree on the tooling design, cost, ownership, storage and modification terms, together with the sample schedule. Approve these details before tooling starts.
Sampling & refinement
Produce trial samples for dimensional, appearance and assembly checks. Review any deviations, agree on changes and repeat sampling where needed; record the approved drawing revision.
Sample acceptance
Evaluate the samples against the agreed dimensions, hardness, color, finish and functional requirements. Confirm the approved reference sample and inspection plan in writing before batch production.
Production & final inspection
Produce to the approved specification. Agree on inspection records, sampling quantities and how nonconforming parts will be handled; confirm batch acceptance and packaging before shipment.
Delivery & receiving checks
Confirm the shipping method and destination. On receipt, check quantity, packaging, part identification and the agreed acceptance items; report any discrepancy with photos and batch details.
