Project 01 / Original Report Data

Ice Tray CAD/CAM Mould Workflow

The original Creo project remains as the first project. It presents a rectangular ten-cavity ice tray designed for two-part injection moulding, including draft and round modifications, mouldability comparison between ABS grades, mould-volume splitting, shrinkage checks, clamp-force preparation and CNC machining simulation.

Step 01

Model Design and Mould-Ready Modifications

Creo Parametric is used to create the ice tray geometry with two rows of cavities, a clean parting strategy, traceability features and manufacturability improvements. The report applies 5° draft, internal 2.8 mm rounds, 1.0 mm cavity-edge rounds and 5.0 mm external corner rounds before validating positive draft coverage.

Step 02

Mouldability and Material Selection

The mould analysis reviews central gate planning, ABS material options, air traps, weld lines, pressure distribution and sink marks. The comparison identifies ABS_POLYMAN E/HI as the stronger optimised option because it reaches excellent mouldability with lower pressure and fewer defect indicators.

Step 03

Mould Split, CAM Setup and Drawings

The mould workflow defines Z-axis pull direction, creates the mould volume, establishes parting surfaces, separates core and cavity, checks shrinkage/clamp-force data and finishes with milling operation setup and technical drawing documentation for the insert and final part.

Project 02 / Dog Bowl Report

Dog Bowl Injection Mould & CAM Workflow

The second project presents a Creo-based dog-bowl mould-design study. It covers a compact injection-moulded dog bowl with branding, hidden ID marking, draft checking, ABS material evaluation, mouldability simulation, two-part mould creation, shrinkage review and CNC milling path verification.

Step 01

Dog Bowl Model Design

The dog bowl is designed within the 100 × 100 × 50 mm size envelope and kept simple for two-part injection moulding. The top includes a “Dog Bowl” logo for identity, while the underside carries the hidden Up2538839 identification mark for traceability.

Step 02

Draft Check and Manufacturability

The report applies a 45° draft concept to help demould the bowl without damaging the cooled part. Draft-check views are used to compare top and bottom surfaces using colour-scale feedback, while the model intentionally avoids extra rounds to keep the component geometry direct and manufacturable.

Step 03

Mould Analysis and Material Selection

Two ABS materials are evaluated: STAREX MP-0660 and Cevian-V 110. The dog-bowl report reviews mouldability, air traps, weld lines, pressure distribution and sink marks for each material, selecting Cevian-V 110 because it provides better pressure distribution and reduced defect risk.

Step 04

Two-Part Mould and CNC Machining

The manufacturing workflow includes a two-part mould, mould opening view, shrinkage ratio setup, cutting tool parameters and simulation of the cutting path for the dog bowl die. This converts the CAD model into a production-oriented mould-and-CAM case study.
