KACL Space Adjustment Collars
Space adjustment collars (KACL) are plastic mold components designed to fine-tune spacing during assembly for accurate alignment. They help molds run smoothly while improving component longevity under operating loads.
- Adjustable fit with selectable outer diameter (D) for assembly flexibility
- Configurable length (L) supports the exact spacing requirement in mold stacks
- Precision bore geometry for stable seating and consistent alignment
- Built under type KACL for reliable use in plastic mold adjustment applications

Product Guide
Application Scenarios+
KACL space adjustment collars are used in plastic injection mold assemblies wherever precise stack-up spacing is needed to achieve repeatable alignment between cores, cavities, and surrounding hardware. In automotive connector and housing molds, they help fine-tune the gap during assembly so mating components seat consistently, reducing misalignment-driven wear over repeated cycles.
- Mold stack spacing adjustment: Select the appropriate outer diameter and configured length to match the required stand-off in the mold’s build-up.
- Alignment stabilization: The collar’s inner diameter supports stable seating on the mating part, helping maintain concentric positioning under handling and clamping loads.
- Component longevity: Correct spacing minimizes rubbing and uneven load transfer, supporting smoother operation and longer service life of adjacent mold parts.
This variant is suited because it offers selectable outer diameter (D = 10–45 mm) and configurable length (L = 5–150 mm or 5–200 mm), allowing engineers to match real assembly tolerances without redesigning the main structure.
Material & Process Details+
The provided specifications describe dimensional ranges for KACL space adjustment collars (D, L, V) but do not state a specific steel grade, surface treatment, hardness, or heat-treatment condition. As a result, the material properties and any heat-treatment state (e.g., quenched & tempered, nitrided, etc.) cannot be stated from the given data.
When selecting a collar for high-load mold areas, engineers typically consider the trade-off between wear resistance and toughness depending on contact pressure and potential rubbing. If you supply the material grade or drawing for this series, we can translate it into the relevant equivalent (e.g., AISI equivalents), expected hardness range (HRC), and the most appropriate heat-treatment state.
- Need material confirmation: Request the material/spec sheet to verify steel grade and treatment.
- Surface/tribology selection: Choose based on whether the collar experiences sliding contact or primarily static seating.
Sizing & Selection Guide+
To select the correct KACL collar for a mold stack, start by matching the outer diameter (D) and length (L) to your assembly envelope and stand-off requirement. The available dimensional ranges are D = 10–45 mm, with L = 5–150 mm or L = 5–200 mm depending on configuration.
Next, match the inner diameter (V) to the mating feature to ensure proper seating and alignment: V = 7–33 mm. Use the inner diameter relationship to confirm clearance/fit for assembly and repeatability during clamp cycles.
- Step 1: Determine the required stand-off/space in the mold stack and select L within the applicable range.
- Step 2: Ensure D fits within the surrounding hardware and does not interfere with nearby components.
- Step 3: Verify V matches the mating shaft/guide (including your required clearance/transition fit).
Where tolerances are critical, confirm the collar’s dimensional tolerances on the drawing and validate fit using your mold assembly stack-up tolerances.
Frequently Asked Questions
How do I choose the correct outer diameter D for a mold assembly space-adjustment collar?+
Select D (outer diameter) so it fits within the available envelope around the collar location while still allowing proper assembly access. This series supports D = 10–45 mm, so pick the value closest to the required outer boundary while checking for interference with adjacent components.
What length L range is available, and how should it be matched to mold stack-up spacing?+
For this KACL series, L is configurable in two ranges: 5–150 mm and 5–200 mm depending on the chosen configuration. Match the collar length to the measured required stand-off in your mold stack-up to achieve correct alignment between parts.
What should I check for inner diameter V (bore) to ensure stable seating and alignment?+
The inner diameter is specified as V = 7–33 mm. Choose V to match the mating feature diameter and provide the intended clearance or fit for assembly repeatability and stable seating during operation.
Can KACL collars be used across different plastic mold product lines without changing the main mold design?+
Yes, because the collar is intended for spacing fine-tuning in plastic mold assemblies. By selecting appropriate D, V, and configurable L within the provided ranges, engineers can adapt the stack-up alignment without redesigning the core/cavity geometry.
Do you provide material grade, hardness, or heat-treatment data for KACL adjustment collars?+
The provided information lists dimensional ranges (D, L, V) but does not include steel grade, hardness (HRC), or heat-treatment details. To specify wear resistance and toughness suitability, request the material/specification sheet for series code 110200136770.
