Dongguan, China – JinYi Mould announces the successful delivery of a BYD mould for an instrument panel lid mould. This dashboard storage mould is the latest addition to our automotive interior mould series, engineered to meet BYD’s strict requirements for visible, high-touch interior parts. The BYD mould project demonstrates how Moldflow analysis can eliminate filling defects and achieve the dimensional accuracy expected of an automotive interior mould.
Project Background: A BYD Mould for the Dashboard Storage Application
BYD needed an instrument panel lid mould that could produce a large storage cover mounted on the dashboard. As a prominent automotive interior mould, the part had to maintain a flawless surface finish while integrating multiple snap-fits and undercuts. The dashboard storage mould also had to withstand repeated open/close cycles without losing tactile quality. This BYD mould was designed with four precision sliders and lifter mechanisms, all validated during the Moldflow analysis phase. No other automotive interior mould in this class allowed for assembly tolerance deviation.
Moldflow Analysis: Eliminating Risk in the Instrument Panel Lid Mould
Before any steel was cut, our engineering team performed a comprehensive Moldflow analysis on the instrument panel lid mould geometry. The Moldflow analysis simulated melt-front progression through thin-walled sections, predicted weld line positions, and mapped warpage displacement across the entire part. Based on the Moldflow analysis results, gate location was moved by 8 mm and cooling channel diameters were adjusted in three circuit zones. This Moldflow analysis-driven optimization reduced predicted cycle time by 12% compared to the initial design, while virtually eliminating sink marks. For this BYD mould, the Moldflow analysis output became the master reference for cooling layout and ejection sequencing. Every automotive interior mould we now deliver follows the same Moldflow analysis protocol to lock process parameters before machining.
Precision Manufacturing of the Automotive Interior Mould
The BYD mould was machined on high-speed 5-axis CNC and wire EDM equipment, holding positioning accuracy to 0.005 mm. To meet the surface requirements of a premium automotive interior mould, the cavity and core were treated with VDI/MT 24 texture on the visible face and mirror-polished (SPI A-1) on the seal-off areas. The dashboard storage mould is optimized for a 320T injection press, well within our 80T–1600T machine park of 18 units. This instrument panel lid mould integrates a balanced conformal cooling circuit and a staged ejection system that releases undercut features without drag marks, guaranteeing stable mass production of the dashboard storage mould. No secondary finishing is required, a direct benefit of the earlier Moldflow analysis and tool design alignment for this automotive interior mould.
Validation: ±0.03 mm on the BYD Mould
Dimensional control was non-negotiable. The instrument panel lid mould went through a structured T0–T3 trial process. At each stage, samples were measured on a bridge-type 3D CMM with a volumetric accuracy of 1.9 μm. The inspection data confirmed that the BYD mould consistently held critical assembly features within ±0.03 mm. Functional testing mated the produced dashboard storage mould components with actual dashboard frames; snap-fit retention force exceeded 45 N, and peripheral gap remained below 0.2 mm. Such data-driven validation is now standard for every automotive interior mould we deliver, especially for a BYD mould that requires full traceability documentation.
Turnkey Dashboard Storage Mould Delivery
JinYi Mould shipped the instrument panel lid mould as a complete turnkey package. The documentation binder included the Moldflow analysis report with simulation-to-actual correlation data, T0 through T3 trial logs, 3D CMM inspection records for 100% of critical dimensions, material certifications, and a maintenance schedule. BYD was able to transition the dashboard storage mould directly into mass production without additional adjustments.
How to Specify Your Next Instrument Panel Lid Mould or Dashboard Storage Mould
If you are developing an automotive interior mould such as an instrument panel lid mould or a dashboard storage mould, the following steps reduce technical risk and accelerate launch:
Moldflow analysis and DFM: Provide your 3D part data. We will run a Moldflow analysis and a full DFM study to define gate, runner, cooling, and venting strategy for your automotive interior mould before any commitment to tooling.
BYD mould precision baseline: Our work on this BYD mould proves that ±0.03 mm tolerance and VDI/MT texturing can be achieved repeatably on an instrument panel lid mould or dashboard storage mould.
Automotive interior mould validation: With 18 injection machines (80T–1600T), we execute T0–T3 trials and supply 3D CMM data for your dashboard storage mould, ensuring every automotive interior mould meets dimensional and assembly requirements.
Turnkey dashboard storage mould delivery: You receive a fully documented dashboard storage mould package with Moldflow analysis records, exactly as delivered for the BYD mould.
By selecting a partner that integrates Moldflow analysis into every automotive interior mould project, you gain process certainty that your instrument panel lid mould or dashboard storage mould will perform from the first shot.
