Focus on Writing is an academic writing program that provides students with essential tools to master not only the key steps in the writing process, but also the grammatical structures, lexical knowledge, and rhetorical modes essential for academic writing.This five-level series progresses with students as they grow in confidence and ability from sentence level (Book 1) through paragraphs (Books 13) and essays (Books 35). Each unit leads writers step-by- step through the process of prewriting, writing a first draft, revising, and editing before producing a final draft. Not only do students write an entire paragraph or essay in each unit, they are also given plenty of practice at the sentence and word levels. Features:Each unit teaches students how to use one or more common organizational structures: narrative, description, opinion, persuasion, compare-contrast, problem-solution, and cause-effect. High- interest readings and a choice of writing assignments provide a springboard for students writing. Grammar presentation and practice correlated to Focus on Grammar make the connection between grammar and writing clear. Building Word Knowledge mini-lessons and exercises teach students how to use word forms, collocations, idioms, compounds, descriptive details, phrasal verbs and other types of vocabulary in their writing. Revision and Editing checklists for each writing assignment help students rewrite and polish their first drafts. Online Teachers Manuals contain model lesson plans, unit overviews, timed writing assignments, authentic student models, and answer keys.

For the first time, both the art and the science of designing runners and gates are presented in a concise format. Tried and true runner and gating design techniques successfully used with various materials and molding applications are described together with cutting edge new technologies. The book will help readers determine when to use what type of runner system and how to isolate molding problems generated by the gate and runner vs. other molding issues. Much emphasis is placed on the critical features in a hot runner design and how to determine what type of design is best for a specific application. Finally, readers will be able to separate the sales hype from reality when dealing with hot runner suppliers.
Obwohl das Angusssystem einen starken Einfluss auf den Spritzgießprozess hat, wird für die Auslegung seiner Komponenten meistens ein relativ geringer Zeit- und Kostenaufwand betrieben. Auch in der Fachliteratur zum Spritzgießen wird die Gestaltung des Angusssystems und dessen Bedeutung oftmals nur am Rande behandelt. Diese Informationslücke wird mit dem Buch „Auslegung von Anguss und Angusskanal“, das nun erstmals in deutscher Übersetzung vorliegt, geschlossen. Zunächst werden die rheologischen Eigenschaften der Kunststoffschmelze anschaulich und praxisnah erläutert. Schritt für Schritt entstehen daraus Strategien für die Gestaltung des Angusssystems und der Anschnittposition. Das Buch beschreibt präzise und detailliert die zahlreichen Gestaltungsmöglichkeiten bei Kaltkanal- und Heißkanalsystemen. Damit bietet es dem Leser eine unabhängige Betrachtung von Heiß- und Kaltkanalsystemen, ohne ein Urteil zu fällen, welches System sich am besten für eine bestimmte Anwendung eignet. Außerdem enthält das Buch einen umfangreichen, praxisorientierten Leitfaden zur Fehlerbehebung beim Spritzgießen.
