Multi-Cavity Precision Mold Bases

Non-standard precision mold bases for multi-cavity layouts require more than a cavity count. Repeated insert seats, locating bores, plate relationships and inspection datums must work together. Lichengda reviews the base plates and machining package against your controlled drawings; finished cavities and cores are listed separately from the base work.

Drawing-Specific Base Machining

Non-standard mold base machining for repeated insert locations, pocket patterns and locating bores, inspected to the agreed datum scheme.

Supply scope
Plate/feature machining
Interface review
Provide the assembly and plate drawings with cavity count, pitch pattern, insert-seat geometry and the current revision. Identify common datums, positional requirements, matching bores and the features to include in dimensional/CMM reporting. Define plate material and condition, machining allowance, guide components, assembly responsibilities and the work remaining with your toolroom.
Overall capacity
Footprint up to 1500×1200 mm; approximately 8 tonnes per set, subject to drawing review

Guide assembly refers to the agreed guide pillar and bushing work. Hot runner systems, hydraulic cylinders, rotation hardware and other purchased mechanisms are not automatically included.

Drawing and Quotation Checklist

  • Provide the assembly and plate drawings with cavity count, pitch pattern, insert-seat geometry and the current revision.
  • Identify common datums, positional requirements, matching bores and the features to include in dimensional/CMM reporting.
  • Define plate material and condition, machining allowance, guide components, assembly responsibilities and the work remaining with your toolroom.

Include quantity, drawing revision, required inspection documents and delivery destination. Single-piece and small-batch inquiries are accepted.

Machining and Interface Review

Repeated locations
Mark the pitch pattern, pocket or insert-seat sizes, depth and corner details. Identify which features are finished and which retain allowance.
Datum and inspection plan
Specify the common coordinate system, inspection temperature/reference conditions where required, and the hole/pocket positions to be reported.
Matching interfaces
Include insert interfaces, guide bores, plate registration and relevant water-channel details in one controlled drawing package.
Base versus finished tool
Quote base machining, any agreed guide assembly, cavity/core manufacture and purchased systems as separate scope items.

Inspection and Production Planning

Dimensional and CMM reports are available for agreed datums and critical features. The drawing review confirms the applicable tolerances, measurement method and acceptance scope. Overall mold-base capacity is up to 1500×1200 mm footprint and approximately 8 tonnes per set, with height, geometry, access and handling reviewed separately.

Production schedule: 7–15 working days; large or complex projects 15–25 working days. Working days exclude weekends and statutory public holidays in China. The clock starts on the next working day after formal PO receipt, final drawing/specification approval and applicable deposit receipt are all completed. Transport time is separate.

Multi-Cavity Precision Mold Bases Questions

What drawings are needed for a custom multi-cavity mold base?

Send the assembly and plate drawings with cavity count, pitch pattern, locating datums, insert-seat geometry, material condition and inspection requirements. PDF, STEP and DWG files are accepted.

How are repeated bore positions checked on a precision mold base?

Agree the datum scheme and the critical bores or pockets before machining. Dimensional and CMM reports can document the specified features; the approved drawing defines the positional acceptance requirements.

Does a multi-cavity mold base include finished cavities and cores?

The base order includes only the plate machining and supplied items agreed in the quotation. Finished cavities, cores, hot runner equipment and other systems are identified separately.

Which precision figures apply to a non-standard mold base?

Published reference capabilities include plate parallelism/flatness of ≤0.02 mm, hole position tolerance of ±0.015 mm and guide-hole coaxiality of 0.01 mm. Applicability to the actual dimensions, datums, features and inspection method must be confirmed on the approved drawing; these are not universal whole-base guarantees.
