Table Mould
With over 20 years of experience in large‑scale injection mould manufacturing, SINOMOULD provides integrated table mould solutions for home, office, outdoor, and other applications. From modern office chairs to structurally robust outdoor leisure tables, our advanced mould flow analysis and precision machining capabilities ensure that every mould achieves efficient, stable mass production.
SINOMOULD’s table moulds are built with the core advantages of long service life, short cycle time, and low maintenance costs—helping furniture manufacturers reduce costs, increase efficiency, and consistently deliver high‑quality plastic tables and chairs in a highly competitive market.

Key Quality Points of Table Mould
To ensure that every delivered table or chair mould achieves unmanned, long‑term stable production at the customer’s site, SINOMOULD implements a stringent full‑chain internal quality control standard:
- Shrinkage and warpage pre‑compensation for large parts
For large planar structures such as tabletops and seats, we apply Mouldflow‑driven pre‑deformation compensation during the design phase. By accurately predicting the shrinkage rate and orientation effects of PP/ABS materials, we counteract the risk of warpage before steel cutting begins, ensuring that the finished part’s flatness meets the strict requirements of furniture assembly.
- Reliability verification for deep‑cavity and undercut demoulding
table moulds often contain complex undercuts such as deep ribs, snap‑fits, and handle features. SINOMOULD performs motion interference simulation on lifter and slider mechanisms and uses optimized friction‑pair materials (H13/S136). This prevents jamming and galling during mass production, ensuring smooth ejection and parts free from white ejector marks.
- Full‑batch hardness and flaw detection of steel
All incoming steel for cavities, cores, and major structural components undergoes HRC hardness inspection and ultrasonic flaw detection. This eliminates the risk of premature mould cracking or failure caused by internal micro‑cracks or uneven hardness, ensuring that table moulds easily exceed the design life threshold of 500,000 to 1,000,000 cycles.
- Multi‑gate timing balance for hot runners
For large‑size table moulds, we use a Yudo valve‑gated timed‑sequence hot runner system. By controlling the opening timing of each gate, weld lines are eliminated, and the melt pressure is transmitted uniformly during gas‑assist or packing phases, eliminating sink marks on thick sections and surface flow marks.
Precision Machining Highlights for Table Mould
A high‑quality table or chair mould is born from precision machining and extensive fitter experience. Relying on advanced 5‑axis machining centers and standardized assembly processes, SINOMOULD has built the following technical advantages:
- 5‑axis high‑speed milling (HSM)
For large curved surfaces and fine texture features, we use 5‑axis high‑speed machining centers for polish‑free precision milling. By replacing polishing with milling, we preserve the original sharp edges of the mould steel. This makes subsequent Mould‑Tech texturing or mirror polishing more uniform and transparent, delivering an excellent furniture surface quality.
- Graphite electrode EDM for corner cleaning and finishing
For transitions, corner radii, and rib roots that cannot be reached by cutting tools, we use high‑purity graphite electrodes for EDM finishing. Combined with mirror EDM technology, we reduce cavity surface roughness, lower melt flow resistance during injection, and protect delicate ribs from sticking or breaking.
- CMM in‑process inspection
From rough machining to final assembly, we strictly perform full‑size monitoring using a gantry CMM. This ensures that cavity/core insert interchangeability is ≤0.02 mm and that slider and lifter fits are precise. It eliminates flash and misalignment caused by accumulated assembly errors, delivering moulds that are ready for optimal mass production from the very first shipment.
