       In an egg tray machine, the mold is not just a tooling component. It is one of the main factors that determines whether pulp is distributed evenly, whether vacuum suction remains balanced across cavities, and whether wet products can be transferred and dried with stable quality.\n      <\/p>\n      <p class=\"rc-mold-text\">\n        When mold design is weak, production problems often appear in the form of uneven thickness, incomplete forming, unstable demolding, higher moisture variation, and more maintenance interruptions. A better-engineered mold helps keep forming performance more predictable across long operating cycles.\n      <\/p>\n      <ul class=\"rc-mold-list\">\n        <li>Defines the shape and dimensional consistency of the molded tray<\/li>\n        <li>Affects pulp adsorption, drainage speed, and dewatering behavior<\/li>\n        <li>Influences reject rate, stacking quality, and drying load<\/li>\n        <li>Supports more stable continuous production and easier maintenance<\/li>\n      <\/ul>\n\n      <div class=\"rc-mold-inline-links\">\n        <a href=\"\/products\/egg-tray-machine\/\">Egg Tray Machine<\/a>\n        <a href=\"\/products\/egg-tray-production-line\/\">Egg Tray Production Line<\/a>\n        <a href=\"\/contact\/\">Contact Richon<\/a>\n      <\/div>\n    <\/div>\n\n    <div class=\"rc-mold-img-wrap\">\n      <img decoding=\"async\" class=\"rc-mold-img tall\" src=\"https:\/\/richongroup.com\/wp-content\/uploads\/2026\/03\/egg-tray-forming-mold-structure.webp\" alt=\"Forming mold structure used in egg tray production line for molded pulp shaping\">\n    <\/div>\n  <\/div>\n<\/section>\n\n\n\n<section class=\"rc-mold-section deep\" id=\"main-mold-types\">\n  <div class=\"rc-mold-container\">\n    <div class=\"rc-mold-center\">\n      <span class=\"rc-mold-tag\">Core Mold Types<\/span>\n      <h2 class=\"rc-mold-title\">Main Mold Types in a <span>Pulp Molding Line<\/span><\/h2>\n      <p class=\"rc-mold-subtitle\">\n        Different mold positions perform different tasks in molded pulp production.
