Injection Molding
Tooling and molding for your repeat plastic parts.
YOUR BORE. YOUR BOLT PATTERN. YOUR FINISHED FIT.
Custom Throttle Body Spacer Manufacturing
For your intake or performance-parts brand, define the spacer around your retained throttle body and manifold. Send bore geometry, mounting patterns, final thickness and gasket references so your throttle body spacer manufacturer can review the complete machining requirement.
Bore geometry
Profile and alignment
Mounting pattern
Holes and fastener access
Sealing faces
Gasket and flatness
Installed space
Thickness and clearance
Custom mechanical spacers · No universal fit or horsepower claim
3 Spacer & Adapter Configurations
Choose the interface you need to reproduce or connect, then provide its approved geometry.
Smooth-Bore Spacers →
Define the passage, face geometry and mounting holes from controlled mating references.
Specified-Thickness Plates →
Control final thickness together with clearance, fastening and intake alignment.
Interface Adapter Plates →
Identify both mounting patterns and any passage transition required by your approved design.
4 Inputs for Your Spacer Quote
A nominal throttle diameter does not define hole locations, gasket fit or installed clearance.
Mating references
Provide throttle body and manifold interface drawings or approved dimensional references.
Released drawing
Identify bore, hole pattern, thickness, face requirements and controlled revision.
Installed envelope
State retained hardware, available clearance and assembly access requirements.
Order definition
Provide grade, finish, quantity, sample objective and required inspection records.
3 Machining Decisions for Your Spacer
Connect the passage, fastening and sealing requirements in one released drawing.
Bore & transition
Specify the final profile and its alignment with both retained mating parts.
Holes & fasteners
Define through holes, counterbores or threads and the required engagement envelope.
Sealing & finish
Mark gasket seats, face flatness, surface requirements and protected zones.
3 Material & Finish Decisions
Select the specified material for your design and environment; appearance cannot identify it.
Exact alloy
Specify grade, temper and stock form. EN AW-6061 is a designation reference; confirm the applicable purchasing specification.
Final condition
Agree anodizing or other finish, appearance zones and any masking of sealing or threaded features.
Application requirements
Identify temperature, exposure and mating materials. Any thermal or airflow performance requires separate validation.
4 Checks Before Your Spacer Sample Approval
Keep dimensional acceptance separate from engine performance or emissions approval.
Pattern alignment
Compare hole locations and passage alignment with the released datums.
Thickness & faces
Confirm final thickness and specified flatness or parallelism.
Gasket & hardware fit
Review the approved seal reference, fastener access and installed clearance.
Acceptance records
Agree reported dimensions, material evidence and any application-specific tests.
4 Steps to Your Repeat Spacer Order
Retain the mating references and sample decisions your next batch must follow.
Share controlled inputs
Send CAD, drawing, mating references and planned quantities.
Confirm the quotation
Agree material, machining, final finish and inspection scope.
Approve your sample
Review fit and finish and complete the validation required by your application.
Release repeat supply
Retain the approved revision, appearance reference, identification and packing requirements.
China Manufacturing · Dallas–Fort Worth Support
For your throttle body spacer program, distinguish where the part is made from where your project communication is supported.
Dongguan Manufacturing
Your Project Coordination
Dallas-Area Support
Agree who owns the drawing and sample approval.
Confirm packing, delivery terms and import responsibilities.
Discuss local coordination and any inventory arrangement.
Genuine company and customer-discussion photographs. Manufacturing in China; U.S. support does not mean U.S. manufacture or a default local stock program.

6 Answers Before Your Spacer RFQ
Resolve mating geometry and approval scope before production.
What should my throttle body spacer manufacturer receive?
Provide CAD, controlled drawing, bore geometry, both mating interfaces, final thickness, gasket requirements, material, finish and quantities.
Can one nominal bore size establish fit?
No. Hole patterns, passage alignment, gasket geometry, thickness and retained hardware must also be defined.
Does a spacer guarantee more horsepower?
No. This page describes manufacturing scope. Power, airflow and vehicle-system effects require application-specific validation.
How should I specify gasket contact faces?
Mark the actual gasket reference and required surface, flatness and final dimensional conditions on the drawing.
Can hardware be chosen after the spacer is made?
Define retained hardware and engagement requirements during design review. The additional stack thickness can change fastener and clearance requirements.
Are prototypes and repeat orders available?
Provide both quantity plans for review. Material, process, sample scope and delivery terms are confirmed in your quotation.
